I think what you said about condoms highlights a key historical difference. Throughout most of humanity's moral development, there was no such thing as protection, against STDs or pregnancy, other than the rhythm method or induced abortion. Definitely, there was wisdom in limiting the number of partners and orifices in much of that time.

Edit: which is to say, technology can affect morality and there's a good reason for these attitudes to change now.

Also, what you said about Jesus and poverty is spot-on. I really wish more Christians would embrace the truly good and radical parts of Christianity instead of fixating on arcane moral rules.
