I visited a Methodist Church where Transubstantiation was indicated before taking Communion.
We make a mistake when we try to box all of the various groups into one box. Even for those that adopt a name in their fellowship, there's no guarantee their doctrine even resembles the group they claim to be. Most fellowships will present the doctrine of their leaders, and quite a bit of evolution can go on down through the centuries.
There is a true line of True Doctrine from Paul's day, and it derives straight from the Word of God. If we have maintained what was taught to us by the Writers, and ultimately the Holy Ghost, then we have maintained that Pure Doctrine.
The problem we face is that no one group is going to be correct...on everything. Some are correct on more, but there are going to be issues with any group you want to name.
Salvation remains personal. A person can be a member of a group and not have to dogmatically embrace everything they teach. And that is just normal for a people who still battles the presence, impact, and consequence of sin in our lives. We are still going to see rebellion, and failure to maintain a strict discipline.
God bless.
