Herein lies the crux of the problem. I can understand that you did not really believe Jesus was who he said he was while you attended church, and later came to repentance and faith. Changing from Baptist to Presbyterian makes no sense and shows the fundamental flaw in Protestantism; it really is a continuous protest without apostolic succession.
How so?
What do the major historians of Protestantism say? Like almost all their colleagues, John Dillenberger and Claude Welch link the origin of the word Protestant to the ‘Protestation’ of the German evangelical estates in the second Diet of Speyer. But they see in that term “the duality of protest and affirmative witness.” That protest, they write, wasfrom the standpoint of affirmed faith. Few churches ever adopted the name “Protestant.” The most commonly adopted designations were rather “evangelical” and “reformed.” ... [W]hen the word Protestant came into currency in England (in Elizabethan times), its accepted significance was not “objection” but “avowal” or “witness” or “confession” (as the Latin protestari meant also “to profess”).That meaning lasted for another century, say Dillenberger and Welch, and it referred to the Church of England’smaking its profession of the faith in the Thirty-nine Articles and the Book of Common Prayer. Only later did the word “protest” come to have a primarily negative significance, and the term “Protestant” come to refer to non-Roman churches in general.-- from the thread History Lesson: Positively Protestant
