The Council of Chalcedon (451 AD): Canon XV

A woman shall not receive the laying on of hands as a deaconess under forty years of age, and then only after searching examination. And if, after she has had hands laid on her and has continued for a time to minister, she shall despise the grace of God and give herself in marriage, she shall be anathematized and the man united to her.

Ancient Epitome of Canon XV.

No person shall be ordained deaconess except she be forty years of age. If she shall dishonour her ministry by contracting a marriage, let her be anathema.

This canon should be read carefully in connexion with what is said in the Excursus on deaconesses to canon xix. of Nice.

This canon is found in the Corpus Juris Canonici, Gratian’s Decretum, Pars II., Causa XXVII, Quæst. I., Canon xxiij.
