“We decree moreover that no Christian shall compel them or any one of their group to come to baptism unwillingly. But if any one of them shall take refuge of his own accord with Christians, because of conviction, then, after his intention will have been manifest, he shall be made a Christian without any intrigue. For, indeed, that person who is known to have come to Christian baptism not freely, but unwillingly, is not believed to posses the Christian faith.”  Pope Gregory X, On the Protection of the Jews, 1272 A.D.
