Oséias 6

Oséias 6:2

Hear what the prophet says: "God will revive us after two days, and on the third day we shall arise and live in his sight." The first day is the passion of the Savior for us. The second is the day on which he descended into hell. The third day is the day of resurrection. Therefore on the third day "God went before them, by day in a column of cloud, by night in a column of fire." But if according to what we said above, the apostle teaches us rightly that the mysteries of baptism are contained in these words, it is necessary that "those who are baptized in Christ are baptized in his death and are buried with him." [They must] also arise from the dead with him on the third day, according to what the apostle says, "He raised up together with him and at the same time made them sit in the heavenly places." When, therefore, you shall have undertaken the mystery of the third day, God will begin to lead you and will himself show you the way of salvation. — HOMILIES ON EXODUS 5
