Assumption and conjecture aren’t what Christ taught nor did the apostles. Christ Himself referred back to scripture to support what He taught as do I. Base your beliefs on conjecture and assumption if you will. I’ll stay with scripture.
You are free to believe what is in the Scripture, but there is much that you believe that is not in Scripture, including what is Scripture. The Gospels tell us what happens up to the time of the Ascension into Heaven. Acts tells us something of the history of the early Church, but disappoint, because in the case of Peter et al, the native cuts away from him as if, the sincere reader will see, to take it up at a later time. Ditto what happens to Paul, after he comes to Rome. Why leave us hanging? Because Acts is a fragment. The author tells us what he knows, and that is far from being the whole story. The letters by Paul and others attributed to him, are occasional pieces, sermons, and in the case of Romans, something like a treatise. Revelation is an apocalypse, one of a kind, but Christian rather than Jewish as are several others of the time. All this writing is evidence, but evidence, as any lawyer can tell you, is putty in the hands of its interpreter. You, sir, are full of conjecture, but cannot admit it.
"The Assumption" not an assumption. Please stay protestant, it would be an embarrassment to have you as a Catholic
