Saint Ignatius of Antioch, AD 50-117
“Try to gather more frequently to celebrate God’s Eucharist and to praise Him. For when you meet with frequency, Satan’s powers are overthrown and his destructiveness is undone by the unanimity of your faith...Where the pastor is, there follow like sheep. For there are many specious wolves who… capture those who run God’s race...If anyone is not inside the sanctuary, he lacks God's bread. Be on your guard; .... inside the sanctuary a man is pure; outside he is impure. Whoever does anything without the bishop... does not have a clear conscience."
