Much confusion resulted from (and contributed to) last week's quick overview of a variety of Communion practices. Here's more information on Catholic and Orthodox traditions, as well as other reader feedback.
June 28, 195: Irenaeus, bishop of Lyons (France) and one of the most important Christian writers of the second century, dies. He argued that tradition is key in sustaining orthodoxy, and he was instrumental in raising the authority of the Roman bishop. He was also the first to add the four Gospels to a list of apostolic writings, calling them "Scripture" with the Old Testament. Many consider him the first theologian of the Christian church, since others were more apologists than theologians.
