Nicene and Post-Nicene Fathers, Vol. III:
Moral Treatises of St. Augustin: Section 1

Augustin the Bishop, servant of Christ, and of the servants of Christ, unto the religious handmaiden of God, Juliana, in the Lord of lords health.

Not any longer to be in debt of my promise to your request and love in Christ, I have seized the occasion as I could, amid other my very pressing engagements, to write to you somewhat concerning the profession of holy widowhood, forasmuch as, when I was present, you laded me with entreaty, and, when I had not been able to deny you this, you often by letters demanded my promise. And in this work of ours, when you shall find in reading that some things pertain not at all unto your own person, or unto the person of you, who are living together in Christ, nor are strictly necessary to give counsel unto your life, it will be your duty not on this account to judge them superfluous. Forsooth this letter, although it be addressed to you, was not to be written for you alone; but certainly it was a matter for us not to neglect, that it should profit others also through your means. Whatsoever, therefore, you shall find here, such as either hath been at no time necessary for you, or is not so now, and which yet you shall perceive to be necessary for others, grieve not either to possess or to lend to read; that your charity also may be the profit of others.
