I have now finished reading 'Misquoting Jesus'. The other triad of reasons why the early scriptures were altered are "social" rather than theological. They include the role of women in the Church, the antagonism between Christians and Jews and polemics between Christians and pagans. In regards to the first question the early Church varied in its practices. In some congregations women and men were more equal than in others. It's interesting that versus attributed to Paul such as 1 Timothy 2 (likely to have written by a 2nd ! generation follower of Paul rather than the apostle) and 1 Corinthians 14 (likely to have been inserted from a marginal note on a ms) are doubtful. The latter passages are in different places in different mss, are out of context in the letter and contradict other verses in 1 Corinthians. The passage about wearing veils while speaking in Church is considered authentic, but 1 Corinthians 14 seems to forbid women from speaking in Church ie he forbids what he has already given instructions for.
There are a number of other alterations mentioned.
More later.
