Today is the feast of Pope St. Leo I the Great, Doctor of the Church. From one of his Easter sermons, Sermon 71:
Let God's people then recognize that they are a new creation in Christ, and with all vigilance understand by Whom they have been adopted and Whom they have adopted. Let not the things, which have been made new, return to their ancient instability; and let not him who has put his hand to the plough forsake his work, but rather attend to that which he sows than look back to that which he has left behind. Let no one fall back into that from which he has risen, but, even though from bodily weakness he still languishes under certain maladies, let him urgently desire to be healed and raised up. For this is the path of health through imitation of the Resurrection begun in Christ, whereby, notwithstanding the many accidents and falls to which in this slippery life the traveller is liable, his feet may be guided from the quagmire on to solid ground, for, as it is written, the steps of a man are directed by the Lord, and He will delight in his way. When the just man falls he shall not be overthrown, because the Lord will stretch out His hand. These thoughts, dearly-beloved, must be kept in mind not only for the Easter festival, but also for the sanctification of the whole life, and to this our present exercise ought to be directed, that what has delighted the souls of the faithful by the experience of a short observance may pass into a habit and remain unalterably, and if any fault creep in, it may be destroyed by speedy repentance. And because the cure of old-standing diseases is slow and difficult, remedies should be applied early, when the wounds are fresh, so that rising ever anew from all downfalls, we may deserve to attain to the incorruptible Resurrection of our glorified flesh in Christ Jesus our Lord, Who lives and reigns with the Father and the Holy Ghost for ever and ever. Amen.
