Ch. 3 from The Truth of Our Faith:: A Discourse from Holy Scripture on the Teachings of True Christianity, By Elder Cleopa of Romania
Inquirer: What is the Holy Tradition that the Orthodox consider to be the second source of Holy Revelation and coequal with Holy Scripture?
Elder Cleopa: Holy Tradition is the teaching of the Church, God-given with a living voice, from which a portion was later written down. As with Holy Scripture, so, too, Holy Tradition contains Holy Revelation, and is, therefore, fundamental for our salvation. Holy Tradition is the life of the Church in the Holy Spirit and, consonant with the enduring life of the Church, is thus a wellspring of Holy Revelation, such that, consequently, it possesses the same authority as Holy Scripture.
