Roman Catechism 21.45

Chapter 21 — Part II: The Sacraments — Holy Orders

Section 45. The various duties that pertain to the subdeacon are indicated by the solemn ceremonies used at his ordination. In the first place the Bishop warns him that the obligation of perpetual continence is attached to this order, and declares that no one is to be admitted among the subdeacons who is not ready and willing to accept the obligation in question. Then, after the solemn recitation of the Litanies, the Bishop enumerates and explains the duties and functions of the subdeacon. Thereupon each one of those who are being ordained receives the chalice and sacred paten from the Bishop; and, to show that he is to serve the deacon, the subdeacon receives from the archdeacon cruets filled with wine and water, together with a basin and towel with which to wash and dry the hands. At the same time the Bishop pronounces these words: See what sort of ministry is entrusted to you; I admonish you therefore, to show yourself worthy to please God. Other prayers follow, and finally, when the Bishop has clothed the subdeacon with the sacred vestments, for each of which there are special words and ceremonies, he gives kiln the book of the Epistles, saying: Receive the book of the Epistles with power to read them in the Holy Church of God, as well for the living as for the dead.
