By Brian Kranick, Catholic Exchange - Some pro-choice advocates use the Church’s greatest theologian, St. Thomas Aquinas, to argue in favor of abortion. Nicholas Kristof did it in a May 2017 N.Y. Times column about Dr. Willie Parker, an oxymoronically called “Christian Abortion Provider.” Mr. Kristof falsely claimed that St. Thomas Aquinas “believed that abortion was murder only after God imbued fetuses with a soul, at 40 days or more after conception.”
