So, for the 1500 years from the third century until the nineteenth century, there was no true CHURCH? God let His children go without dircetion for 1500 years?! I simply will not accept that.
Then how do you explain the constant Bible passages claiming there is only one God?
Catholic doctrine HASN'T changed. It has developed, but not CHANGED. For instance, Papal infallibilty wasn't always taught in the exact form as it is now, but it has always been believed. I would dare you to find one doctrine of the Church which has "changed".
By the way, saying "we only believe in early church teachings if we see them in the Bible" is a little silly. Obviously, if ALL THESE CHURCH FATHERS believed doctrines (doctrines which you don't believe in by the way) then they must have found them in the Bible, or from the teaching of the Apostles. The entire early church (which you keep referring to as "Christ's church) cannot be wrong, can it? If so, it really isn't
Christ's church and there must never have BEEN Christ's church until the Mormons came along, and that jsut doesn't make any sense for Jesus to come to Earth and then wait 1800 years to establish His church.
Well whatever. It does not make a difference to me.
