An Apology, ecclesiastically speaking, is an explanation and guarded defense of the faith. The Greek word apologia can be rendered as "reply", or "answer" and is a discovered pattern in the Holy Bible, such as Acts 22:1 and I Corinthians 9:3.
The earliest apologists were the Church Fathers. There apologies cover a wide range of topics including the Divine origin of the Church, Christ's Nature, Scripture, the Theotokos, miracles, Christian social interaction and the function of doctrine.
