I was recently having a conversation with a Catholic where he told me that a person cannot be Christian and support legal abortion. My position is that if a person believes in everything in the Nicene Creed including that they believe in God, the Father Almighty, the Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all worlds, who, for us men and for our salvation, came down from heaven, and was incarnate by the Holy Spirit, suffered and was buried; and the third day He rose again, and believes in the Holy Ghost, the Lord and Giver of Life; who proceeds from the Father and the Son; who with the Father and the Son together is worshipped and glorified they are a Christian regardless of their position on the legality and morality of abortion. He told me these people are not Christians. To him they are heretics or at best “fallen-away Christians” but not real Christians.
Is this a common belief among Catholics? Does the Catholic Church take the position that anyone who supports the legality or morality of abortion is not a Christian? Are Catholics who support legal abortion not real Catholics (this was another position of his)? Is there difference between supporting the legality of abortion as opposed the morality of abortion as far being a real Christian in the view of the Catholic Church?
