Here’s a link to the letters of St Ignatius of Antioch. Today (just about) is his feast day. St Ignatius is my confirmation saint, and was bishop of Antioch until he was martyred in 107AD. Some say he was one of the little children Jesus blessed. He wrote his seven letters on his way to martyrdom in Rome, and I strongly recommend them.
St. Ignatius of Antioch, pray for us!
God bless you
