Canon 14 Minimum ages for presbyter, deacon and deaconess

Let the canon of our holy and God-bearing Fathers prevail in this also: that a presbyter be not ordained before thirty years of age, even if the man be altogether worthy, but that he be kept waiting. For the Lord Jesus Christ was baptised in his thirtieth year, and began to teach. Likewise let neither a deacon be ordained before twenty-five years of age, nor a deaconess before forty years of age.
