The trouble is jake, the Christian church has long argued about when a foetus is considered life. In the 4th Century, St Augustine stated that abortion should only be deemed wrong if the foetus is fully formed. He considered this 40 days for a male and 80 days after conception for a female.
Thomas Aquinas in the 13th Century stated abortion was acceptible if it occured before the infusion of the human soul took place. He calculated this was between 40 and 80 days after conception. In 1588 Pope Sixtus V stated the human soul began at the moment of conception, but this was overturned by Pope Gregory XIV three years later, who returned the church to the Thomas Aquinas model.
It was only in 1869 that Pope Pius IX took the church once more towards the moment of conception model of a human life/soul infusion and deemed any abortion an excommunicable act.
