Clement of Rome, Ante-Nicene Fathers Vol. VII, Constitutions of the Holy Apostles… (1885)
“ XIV. Concerning virginity we have received no commandment; [11] but we leave it to the power of those that are willing, as a vow: exhorting them so far in this matter that they do not promise anything rashly; since Solomon says, “It is better not to vow, than to vow and not pay.” [12] Let such a virgin, therefore, be holy in body and soul, as the temple of God, [13] as the house of Christ, as the habitation of the Holy Spirit. For she that vows ought to do such works as are suitable to her vow ”
