Divine Office | The preaching of the Apostles

In today's Office of Readings we encounter a reading from a treatise "On the Prescription against Heretics" by Tertullian, priest (ca. 155-240 A.D.). If you believe in the Trinity, then you owe the word's origin (Trinity) to Tertullian. In fact, nowhere in scripture will you find the word "trinity." Tertullian argued that God was a Trinity (trinitas), a word that he was the first to use. He contributed some of the key ideas and vocabulary of the orthodox understanding of the Trinity, eventually formalized at the Councils of Nicaea (315) and Constantinople (381). His writings played an important part in the shaping of Christian doctrine. For a reflection, "The preaching of the Apostles" please click on the image. Peace be with you!
