So, your entire
"Systematic Theology" is based on a premise where you believe (again) that the Canon of Scripture was defined by a
unknown, leaderless, amorphous mob of "universal Christians..... and the only retort you'd like to make is that
eventually there was corruption in this mob.... but I guess it's no longer a mob, it's Roman Catholic....
when exactly the universal becomes Roman Catholic,
who knows?..... but you can be sure that when it became corrupted,
by THEN it was Roman Catholic..... is that about right?
