So: what are the IMMEDIATE effects of an inability to faithfully preserve Paul's Epistles? All of them are equally significant and have influenced the course of human history far more drastically than probably any other historically ancient document (save the four Gospels themselves) but the one that seems to stand out as the "centerpiece" of Christian theological understanding has always been argued as Romans.
Let's presuppose that Romans is unable to be faithfully preserved. What does Christianity look like?
