All the Bible says is that she was betrothed and appeared surprised that she would become pregnant. The rest is connecting the dots. We do it historically, and the Protestants do it counter-historically to serve their theological fantasies
So true. A woman could not have a job or be single, as you said. That is, by the way, the reason why Muslims "justify" their polygamy. This is yet another good example that someone born in West Virginia in 1985 cannot just pick up the Bible and "understand" it in the context of the culture, mindset and times in which it was written. The Church, on the other hand, was there, in context in every way, and was part of the culture.
Essentially, the Protestant protest is denying those who were with the Church all along that they know anything about her, that even the Church does not know who She is! This is like someone saying to you: annalex, you are not the person you think you are. Your memories are 'flawed.' I know, because I read about you in a newspaper!
What about Lydia? She seemed to be doing quite well, even running a business. I imagine it was more common than you think, and really, putting that type of mindset upon Protestants is quite baseless.
