your flakey sources that are "seriously warped" and out of date
Probably not that much out of date, and I think I have met people certainly from the fringes of that segment of Christianity, as well as talked with others, who perhaps know more than I do. I well recall staying the night at the home of a Pentecostal pastor, and his bewailing the Charismatic Movement of that time because he perceived it as phoney - not the gifts of the Spirit, in which, of course, he firmly believed, but what was going on under that name in the movement which largely arose and grew in the 1960s and today has become so widespread.
One must, I think, gather such information as one can and assess it to the best of one's ability and integrity. The alternative, surely, is to spend a lifetime experiencing first-hand every religion and every denial of religion, not excluding agnosticism, and then every 'segment' of the religion one fixes on as true - in the case of Christianity, Orthodox, Catholic, Calvinist, Arminian, Pentecostal, new-wave megachurches, to mention just a few. One would be forever learning and never coming either to the truth or even to a stable decision.
If the features of which I have heard or read, and which some of you have reported on this thread, are indeed true, then yes, I see that form of Christianity as warped. I am not saying it is peopled by unsaved people who all currently lie outside of God's love and grace, but I am saying that the churches are seriously dissimilar from New Testament churches, not simply in cultural terms, but in fundamental attitudes to God and his service and worship.
And even if my sources are so flakey that they correspond to nothing in the real world, it would still be true (IMHO), that if ever such churches as some of these posts portray should come into existence, their religion would at best be a warped version of the apostolic faith once delivered to the saints.
