The first 1000 years of Church history are undisputed. The next 1000 get tricky. This forum focuses on what is in common between denominations and codifies it into the rules.
The Orthodox Church considers it foolish, if not heretical, to enforce celibacy for Priests, for example. But Catholics have been doing it for nearly 1000 years and this forum isn't going to make a rule about it. This is an example of where it is fine to disagree.
But things that have been in agreement for an extremely long time, such as the Eucharist and Baptism being a part of salvation, or why worship is on Sundays, or why there are hierarchies, aren't up for debate. Homosexuality is obviously included in this - and so is race.
Is there a grey zone where one man's dogma is another man's opinion? Certainly, and I do my best to avoid that. There is no perfect system to judge but I do my best with feedback from other members here, and prayer to God.
It is certainly better to create boundaries on dogma the best we can, and err here and there, rather than not try at all and have a Pagan forum.
