But all the other frenzies of passions-impious both toward the bodies and toward the sexes-beyond the laws of nature, we banish not only from the threshold, but from all shelter of the Church, because they are not sins, but monstrosities.

TertullianIn our case, murder being once for all forbidden, we may not destroy even the foetus in the womb, while as yet the human being derives blood from other parts of the body for its sustenance.

That is a man which is going to be one; you have the fruit already in the seed.
Tertullian
