The divinity of Jesus is not a textual error, it is a translation and interpretive error. I often do my own studies in Greek, but if there is ANY question then I consult experts. But I try to get a balance by reading experts from differing theological perspectives (Ehrman and Metzger being big time sources, although there are many others).
Beyond textual matters and the aforementioned divinity of Jesus, I respectfully decline salaried clergy, church buildings, 'Christian' holidays with pagan origins, special dress for worship, gender segregation, creeds, tithing, worship 'services', systematic theology and a few other odds and ends.
