What are you talking about: there's a Pauline epistle at every service and as you know, Paul is the true "gospel" of Calvinists.
I know, I'm ALWAYS forgetting that!
[15] And account the longsuffering of our Lord, salvation; as also our most dear brother Paul, according to the wisdom given him, hath written to you:[16] As also in all his epistles, speaking in them of these things; in which are certain things hard to be understood, which the unlearned and unstable wrest, as they do also the other scriptures, to their own destruction.
-- 2 Peter 3:15-16
