Belief in TULIP and all that other rot constitutes "following Calvin," since he is the one who made it all up.
Contrary to what Papists* believe, Calvin did not formulate the 5 points of TULIP.
*followers of the Pope, whomever that may be at any given moment.
More off-point tripe.
But, at least it is now well-established that the Catholics themselves don’t permit Paul his place and ignore the clear teaching of Scripture.
