So does Catholic theology teach that the soul enters the body at the moment of conception?
God made us body and soul, when our body was made at conception were we given our soul.
Post 2 has the authoritative answer.
Here is what I was looking for:
"Early in the 13th century, Pope Innocent III stated that the soul enters the body of the fetus at the time of "quickening" - when the woman first feels movement of the fetus. After ensoulment, abortion was equated with murder; before that time, it was a less serious sin, because it terminated only potential human life, not human life.
"St. Thomas Aquinas (1225-1274) also considered only the abortion of an "animated" fetus as murder.
Is the official teaching of the Catholic church now different?
