Sanctify, O Lord, the gifts we offer, and cleanse us from the stains of our sins. Through Our Lord Jesus Christ, Thy Son, who liveth and reigneth with Thee in the union of the Holy Ghost, God world without end. Amen. (Secret for the Second Sunday after Epiphany).
The priest prays the Secret or Secrets right after the Orate Fratres. Sometimes there is one Secret, sometimes two, sometimes three. The priest reads the Secrets from the Missal. These prayers change day to day. The priest prays the Secrets in a voice which the people cannot hear.
The Secret is the tenth and last prayer of the Offertory.
The Secrets are almost always about the bread and wine that are to be changed into the body and blood of Our Lord. The Secrets always ask a favor of God.
The Secret for the Second Sunday after Epiphany speaks of the bread and wine as “the gifts we offer.” When we ask Almighty God to cleanse us from the stains of our sins, we are thinking about the most pleasing offering our Blessed Lord will make to Him at the Consecration of the Mass. At that time He becomes our great gift to God. In a most special way He is making up for our sins.
