You made the claim that it changed, and you have no other evidence for that than your Qur'an that was written 600 years after the events of Christianity.
https://en.wikipedia.org/wiki/Pliny_..._on_ChristiansPliny then details the practices of Christians (sections 7–10): he says that they meet on a certain day before light where they gather and sing hymns to Christ as to a god. They all bind themselves by oath, "not to some crimes", says Pliny, as though that is what he would have expected; rather, they pledge not to commit any crimes such as fraud, theft, or adultery, and subsequently share a meal of "ordinary and innocent food". Pliny says, however, that all of these practices were abandoned by the Christians after Pliny forbade any political associations (hetaeriai or "fraternities").
Christianity may be "Pagan" to Jews and Muslims, but Muslims have no evidence for their claim that it originally was not how we know it today and only later changed.
