I attended a few national gatherings of the ARBCA (Association of Reformed Baptist Churches of America) and loved the music/fellowship but the preaching sessions did not meet my expectations. Instead of a textual sermon or even a topical focus on a doctrine or such, they focused on in-depth exposition of phrases of the 1689 2nd London Baptist Confession. Word-by-word careful examination. Parsing grammar.
Good, but I would have appreciated that same attention to a bibical verse or phrase. Never preached from a doctrinal statement/confession and never considered focusing on man-made wording/sentences in such as so important. In private I asked why they shifted from the 1644 (which I held to, loosely) to a simple minor revision of the WCF written by non-Baptists. Soon found out I was not welcome to be part of ARBCA
