No, not all the creeds of protestant (and for that matter Roman Catholic) churches are abominations, especially since there is a great deal of agreement with the Orthodox Church.
However, the Orthodox Church remains the Church established by our Lord and His Apostles, and has the fulness of the Christian faith, which “denominations” lack. And Orthodoxy is a lot more than a set of doctrines, but is a way of life—remember the Apostles called the Christian faith “The Way” in the New Testament!
Then you retract this part of what you said in post #120? He was told that he must “join none of them, for they were all wrong...Well, what Smith was told—by whoever—was correct,
Because the nameless entities that spoke to Smith as recorded in Pearl of Great Price, Joseph Smith History, told him in vv. 18-20 that ALL of the creeds of these Christian sects were an "abomination."
These entities didn't parcel out which ones ... just said "ALL."
So, would you say these entities were NOT correct, after all?
