1[January 14. St Hilary, Bishop and Confessor.—Semidouble.]
2[Mass.—In medio Ecclesiæ, as in the Common of Doctors, page xxxii. with a Commemoration of St Felix, M. as follows:]
3Prayer. Concede quæsumus. Grant, we beseech thee, O Almighty God, that the examples of thy saints may animate us to a better life, that we may imitate the actions of those whose solemnities we celebrate.
4[Then, of the B. Virgin.]
5[For St Felix.]
6Secret. Graciously receive, O Lord, the offerings devoted to thee by the merits of blessed Felix, thy martyr; and grant that they may prove a perpetual support to us.
7[For St Felix.]
8Postcom. Quæsumus Domine. We beseech thee, O Lord, replenished with salutary mysteries, that we may be assisted by the prayers of blessed Felix, thy martyr, whose solemnity we celebrate.
9[Should the Feast of St Hilary be transferred to another day, the Commemoration of St Felix is not transferred with it, but always made on this day: which is invariably the case with similar Simple Feasts.]
