Taught by the Apostles

“The Church,” wrote Irenaeus, “having received this preaching and this faith, although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves it. She also believed these points [of doctrine] just as if she had but one soul, and one and the same heart, and she proclaims them, and teaches them, and hands them down, with perfect harmony, as if she possessed one mouth.”

From the beginning, Christians have been urged to hold on to “the faith delivered once for all to the saints” (Jude 3). Yet also from the beginning, some people had begun to misunderstand or misinterpret that faith. After the eyewitnesses and apostles passed away, believers could no longer go for answers to those who had laid the foundations of the church. In every great city, different teachers and leaders claimed to represent true Christianity, each asserting that they maintained the true faith, each appealing to a body of apostolic writings.
