In case you don’t have time to read it Nancy Pelosi here’s an excerpt. . .
From earliest times, Christians sharply distinguished themselves from surrounding pagan cultures by rejecting abortion and infanticide. The earliest widely used documents of Christian teaching and practice after the New Testament in the 1st and 2nd centuries, the Didache (Teaching of the Twelve Apostles) and Letter of Barnabas, condemned both practices, as did early regional and particular Church councils.
So, Nancy, I don’t think the Catholic Church Teachings gets any earlier than the Jesus and the 12 Apostles, which is a little more than 50 years ago.
