of Aniane dedicated the abbey church to the Trinity in 872. Feast days were not instituted until 1091 at Cluny and 1162 at Canterbury and papal resistance continued until 1331. Theology Trinitarian baptismal formula Baptism is generally conferred with the Trinitarian formula, "in the name of the Father, and of the Son, and of the Holy Spirit".
