This indifferentism to belief, worship and life is endemic in secular culture. For example, Jehovah's Witnesses are judged not by their beliefs but by their methods. Their beliefs are generally reckoned to be Christian by the uninformed, their methods not.
All choices are more or less valid and equal.
Church and dogma are now two irreconcilable opposites. It is difficult not to see the marks of Antichrist in all of this. Let us consider this. So if a Jehovah's Witness denies the Trinity and an Orthodox Christian affirms this doctrine and if both groups are considered to be Christian then the doctrine of the Trinity or its denial is entirely incidental to being a Christian. The end result of this generalisation of the Church is atheism, or perhaps humanism with a religious veneer.
