In today's Office of Readings we encounter a reading from the treatise "On the Mysteries" by St Ambrose, bishop. St. Ambrose (d. 397 A.D.) was assiduous in carrying out his office, acting with charity to all: a true shepherd and teacher of the faithful. He was unimpressed by status and when the Emperor Theodosius ordered the massacre of 7,000 people in Thessalonica, Ambrose forced him to do public penance. He defended the rights of the Church and attacked the Arian heresy* with learning, firmness and gentleness. He also wrote a number of hymns which are still in use today. Ambrose was a key figure in the conversion of Saint Augustine of Hippo to Catholicism, impressing Augustine (hitherto unimpressed by the Catholics he had met) by his intelligence and scholarship. *The Arian theology held that the Son of God is not co-eternal with God the Father, and was distinct. The Arian concept of Christ is based on the belief that the Son of God did not always exist but was begotten within time by God the Father, therefore Jesus was not co-eternal with God the Father. As such, all mainstream branches of Christianity now consider Arianism to be heterodox and heretical.   For a reflection, "Instruction on the post-baptismal rites," please click on the image.
