All: please don't post religious flamewar comments to Hacker News. That includes proselytizing in any direction, pro or anti. Such threads are as tedious as they are flamey, and those are the two qualities we can most do without here.

Intellectually curious conversation is an entirely different thing and is of course welcome on this or any topic.

It is not fully correct because St Thomas, who was one of the twelve disciples landed in India and martyred here in India and that's why we have A large autonomous branch, known as the Malankara Orthodox Syrian Church (or Indian Orthodox Church), tracing its roots to St. Thomas the Apostle and has its headquarters in Kottayam, Kerala. We in India just call it Syrian Orthodox church. That part is not shown in the video.

What you mentioned about the denomination is not exactly accurate. The st thomas christians or syrian christians or malankara nasranis in kerala or the malabar region, were part of church of east that follows east syriac liturgy. The Malankara Orthodox Syrian Church (or Indian Orthodox Church) that follows west syriac liturgy is a new church started out of a court case in the 19th century.

So, in short, it's like: was unified st thomas christians from st thomas arrival in the 1st century and under church of east since 4th century when it was organised as independent from church of rome till 15th century portuguese arrival and forced latinisations by them leading to coonan cross oath protest, splitting the community into two: one new catholic faction(84 church out of then 116 churches) using the modified east syriac liturgy and the other faction(32 church out of then 116 churches) under patriarch of antioch, adopting the west syriac liturgy locally called the jacobites. The catholic faction mentioned grew into the current syro malabar catholic church. The orthodox jacobite faction underwent another split when british came in the 18th-19th century and tried to create protestant influence, leading to the creation of the marthoma church, which is a protestant church using a protestantised west syriac. In the 18th-19th century times, if I am not wrong, a small faction from the syro malabar catholic church joined the chaldean syrian church, creating a small archdiocese of assyrian church of the east in kerala. Now in the 19th century, a small faction in this jacobite came into communion with vatican keeping the west syriac litury, forming the syro malankara catholic church. At this time in the 19th century the internal conflict regarding whether to be directly under patriarch of antioch came in the jacobites leading to Malankara Orthodox Syrian Church (or Indian Orthodox Church) faction that was mentioned in the comment above.

Syrian christians in Kerala are not related to St.Thomas. Syrian chritians landed in kerala while fleeing arabic invasion of Syria. (7th century)

Also 'martyrdom' of St.Thomas is debated. The earliest mention of martyrdom of St.Thomas originate from 16th century portugese missionaries who operated in india at that time. not backed by any evidence.

I’m sure a book has been written with this thesis, but I often think that a system like Christianity was somewhat inevitable, sociopolitically.

By this I don’t really mean the specifics of the religion; but rather 1) the idea of universalizing the value all human life and not only certain subsets and 2) a synthesis of ideology and politics with the explicit goal of expanding its domain by means of assimilation, not just conquest.

Now of course the reality didn’t actually play out exactly along those lines, but I think a similar sort of movement probably would have occurred across the Roman Empire, had Christianity not specifically grown.

In other words I have a hard time imagining that the world would have continued with Roman values indefinitely. The world was changing and Christianity was as much a consequence as a cause.

Very interesting to consider in any case!

It's even more interesting when you think about Christianity not as a clear category, but as a cloud of practices, beliefs and institutions in a broader family of religious patterns.

Mircea Eliade asks how Christianity reinterpreted sacred history, myth, salvation. What does Christianity do with motifs older than itself, such as paradise, rebirth, sacrifice? In A History of Religious Ideas [0], he treats the emergence and development of Christianity, including Judaism, early Christianity, Gnosticism, late antiquity, medieval religious forms and also how it interacted with other traditions. I think it complements quite nicely the geographical spread of Christianity by also clarifying what kind of transformations of religious symbols make it recognisable as Christianity across such different contexts.

There's also "Darwin's Cathedral" [1] that analyses religion as group-organizing system, with a focus on Calvinism. Didn't go through it, but seems relevant. It was recommended by Robert Sapolsky in his Introduction to Human Behavioral Biology lecture series [2].

What do you mean?

There is a clear phase in our history which was long and no progress was made "Dark age". In that time religion already existed right?

So what was the speciality of christianity apparently bootstrapping everything else? You could only be religious if you had resources to do so. Could have been filled with something else instead.

Napoleon wrote somewere (i read that in a museum) that education is ncessary to fight religion.

We do not know if it hold us back or not, but it also didn't push us through phases like the dark age.

But religion is primarily for control of the people. Thats why you see a lot of rules in the bible. Like paying 5 silver for raping a woman and having to take her as abride.

reply

There is a control dimension, because humans require some degree of limitations in order to thrive. Ultra-individualism breaks down entirely the moment you think about actual society (like actually considering children) rather than utopian fantasies about how some people want society to work.

That being said, the way anti-religion ppl talk about "control" is so profoundly sloppy and underdefined that it's entirely meaningless. If I try to stop someone from shooting me, am I trying to control them? If I change the the youtube algorithm, did I control them? If I spread a bunch of malaria-resistent mosquitos around, did I control them?

Christianity is evangelical because it believes what it's doing is good and should be shared. If you can only conceptualize this as "control", then I feel sorry that you've internalized the worst and most misery-inducing parts of the last 100 years of western philosophy.

This evangelical quality is a feature of many world religions, including the ones that don't normally get called religion, like the New Atheism movement.

The Dark Ages are kind of a myth. The Eastern Roman Empire (aka. Byzantine Empire) existed through the whole time period up to the beginning of the Renaissance. And while some parts of Western Europe were "dark" (mainly due to Viking and Islamic invasions), Western Europe wasn't and isn't the whole world.

reply

The Dark Ages are dark, because they lack surviving written record; ironically due to advancements in writing technology, where people would begin writing on hides instead of papyrus or chisel stone; this made writing a lot faster, but also had a far shorter life span, particularly because people could wipe the hide clean (after the text was of no use), and then rewrite on it.

Conversely, a lot of the writings of the Antiquity are preserved, in large part due to Middle Eastern scholars. The Dark Ages aren't a myth, but rather what is meant by "dark" is misunderstood.

If you are trying to point out that there was something good with religion or necessasity of it, i'm aware of this argument.

We do not know what would have happened without religion.

Just because some aspects of it was helpful (perhaps) to our current state, doesn't mean you can be against the whole concept of it. I also do not have to bow down to it or see it as a positive because of it. I can easily call it an evil necessaity.

Yeah, agree. But also, how critical can you really be if you are a practicing Christian? What is it that you're critical of exactly, and why doesn't it also apply to your religion, if you're "critical"?

I'm an atheist, but hang out with plenty of Christians (protestants mostly, some catholic) and Muslims, and I have nothing against religion per se, can even see some bright and good things coming out of it, and spent most of my childhood in a church, but I know there are plenty of self-labeled Christian scientific researchers who do practice their religion yet would also call themselves "critical", I can totally see why some folks feels like that's slightly hypocritical or contradicting.

reply

Yes, and that's always been vexing to me. I think the reason is like a combination of brainwashing (indoctrination if you must insist), and the fact that Church does offer comforts that most humans need: a feeling of belonging, a meaning to life (handwavey but real), and the perception of being loved.

I'd join the Church in a heartbeat to get those things if I thought the foundational concepts were real.

gausswho 2 hours ago
Critical thinking, by some boundaries of how you define it, was a threat to power that led to the many schisms the video demonstrates. Suppression of it I find to be endemic in monotheistic organized religions. As an outsider to Christianity, it's always seemed odd to me the fluid boundaries of what you can critique and what you can't while remaining faithful. Most Christians would argue you cannot reason your way to the will of God due to the inherent flaws of humanity. I find that a convenient way of saying 'don't rock the boat'.

As a separate aside, you may be interested to learn about the Manichean faith, which for a short period rivaled Christianity as a kind of syncretic mix of faiths: https://en.wikipedia.org/wiki/Manichaeism

I suspect (but am not expert enough to claim) that Christianity's suppression of reasoning-your-way-to-God is a historical artifact of this rivalry. Manichean faith borrowed the ancient Greek concept of the Great Nous and the concept of the "Five Limbs": Reason, Mind, Intelligence, Thought, Understanding.

Many recovering Christians that remain pious, in my experience, retreat to a kind of uber-faith that is not unlike this concept. "I see truth in all religions".

The Christian churches that retained power said: you don't get to determine that.

reply
acedia000 25 minutes ago
This is largely ignoring the fact that Manichaeism was uniformly and severely persecuted under virtually every empire (and respective theology, or lack thereof) it came into contact with, which the Wikipedia article portrays pretty thoroughly.

Also, this is pretty ignorant of the fact that one of the most significant theological and philosophical movements of recent western history was the Reformation, which was specifically staked on the claim that "reasoning-your-way-to-God" was a fundamental right and responsibility of all believers, not just a limited caste of priests. This had implications far beyond theology, and is arguably the foundation of most western ideas of self-determination to begin with.

Also because the region was conquered by Muslims so it did not last. It was the majority religion of the Asian parts of the Byzantine Empire.

North Africa played a very important part in the development of Christianity. Augustine, Tertullian, Jerome and Origen were North Africans. Monasticism evolved in Egypt.

Way back when I heard someone state that the reason Christianity spread so wildly was because it was foundational to proselytize and convert non-Christians to the faith. That makes complete sense to me.

It's not like it was this passive meme that spread because people who encountered it loved it so much they wanted to join.

This is called being a “universalizing” religion.

The big three universalizing religions are Christianity, Islam, and Buddhism.

You can understand a lot of religious history as just those three religions expanding and displacing other belief systems.

Contrast with non-universalizing religions like Judaism, Hinduism, and Shinto.

No, it's because your education is western-centric and Islamic invasions took over the east. Eastern Christians have been subjected to genocide at the hands of Muslims for 1300 years.

Edit - really, someone is asking for a citation that the Islamic conquests happened? Next should ask for a citation that the sky is blue...

This is basic world history, like the discovery of the new world, Alexander the Great's conquests or the Roman empire...

And yes, it happened over 1300 years ago, the first decisive battle was the Battle of Yarmuk, year 636 CE.

I have recently noticed (especially over the last year) a lot of mainstream stories portraying Christianity as growing significantly, things like Instagram posts, tweets, etc., with phrases like “Christianity is back”, you get the idea.

I’m not really sure to what extent this is accurate, though, since those platforms are obviously shaped by my own algorithm. For example, Instagram knows I’m Catholic, so it tends to show me Catholic-positive content.

Does anyone know of a reliable source where I can check the actual numbers? I’m especially curious about Gen Z, since it seems to be relatively pro-Christian.

after non-trivial inquiry from far-away California, my best understanding is that the Celts did gracefully embrace the Christian faith among the monks and those serious about religious life. Since there were vivid and lived religious traditions alive at all times through history, this transition was not uneventful. However the kind of "top down" and by-the-sword conversion that did occur e.g. the Baltic tribes, was not the case with the equally fierce Celts
reply

But the graphic suggests that Celtic Christianity was in some sense theologically distinct from Chalcedonian Christianity, and that doesn't seem to have been the case. The main ways that the Christians of Ireland and Britain differed from those of continental western Europe seem to have been in the shape of the monastic tonsure and the calculation of the date of Easter; and in the latter, at least, British and Irish Christians were in conformity with Rome by the end of the eighth century. (There was also an emphasis on penance and absolution as a private rather than public rite, but this was ultimately adopted by the wider church.)

There doesn't seem to have been any doctrinal disputes, nor any suggestion that British and Irish Christianity was in any way separate from the Church of Rome.
