Being apostolic would mean that they retained the teachings of the apostle. Even Today, with all of the manuscripts and historical evidence, it is still difficult to determine just how closely the teachings of the Apostolic Fathers resembled to or agreed with Jesus’ teachings. The objective of these men was undoubtedly altruistic (noble), seeking to protect or support (make known) a certain orthodox Christianity. They denounced idolatry and loose morals. They believed that Jesus is the divine Son of God and that he was resurrected. However, they were not able to hold back the growing wave of apostasy. Sadly, being honest, some of them contributed to it.
