Chapter 21 — Part II: The Sacraments — Holy Orders
Section 46. Deacon — The second degree of Sacred Orders is that of the deacons, whose functions are much more extensive and have always been regarded as more holy. His duty it is to be always at the side of the Bishop, guard him while he preaches, serve him and the priest during the celebration of the divine mysteries, as well as during the administration of the Sacraments, and to read the Gospel in the Sacrifice of the Mass. In former times he frequently warned the faithful to be attentive to the holy mysteries; he administered our Lord's blood in those churches in which the custom existed that the faithful should receive the Eucharist under both species; and to him was entrusted the distribution of the Church's goods, as well as the duty of providing for all that was necessary to each one's sustenance. To the deacon also, as the eye of the Bishop, it belongs to see who they are in the city a that lead a good and holy life, and who not; who are present at the Holy Sacrifice and sermons at appointed times, and who not; so that he may be able to give an account of all to the Bishop, and enable him to admonish and advise each one privately, or to rebuke and correct publicly, according as he may deem more profitable. He should also read out the list of the catechumens and present to the Bishop those who are to be admitted to orders. Finally in the absence of a Bishop or priest, he can explain the Gospel, but not from the pulpit, thus letting it be seen that this is not his proper office.
