with our minds renewed to the love of heavenly things. We are commanded to keep it in the third week of the same month, because Christ, who had been promised before the Law, and under the Law, came with grace, in the third age of the world, to be slain as our Passover; and rising from the dead the third day after the offering of his passion, He wished this to be called the Lord's day, and the festival of his resurrection to be yearly celebrated on the same. For we also, in this manner only, can truly celebrate his solemnity, if we take care with Him to keep the Passover, that is, the passage out of this world to the Father, by faith, hope, and charity.
