Reflect, that in our fallen and weak state some means of constant reparation was necessary to counteract our daily loss of grace and fervour, too apt to evaporate of themselves, and still more to be diminished and dried up by our hourly negligences and transgressions.

Prayer, meditation, the Word of God, and many other resources were indeed at hand, ready for our use.

But then all these depended for their efficacy upon ourselves, on our fervour and diligence, and were subject to the failings which rendered renovation of spirit and grace most necessary.

The mercy of God soon found the remedy in the institution of the blessed Eucharist, in which the efficacy lies in the Holy Sacrament itself, containing, as it does, the sacred Body and Blood of our ever blessed Redeemer.

He knew how cold our hearts habitually are, and, therefore, instead of telling us to draw nigh unto His warmth, that of it we might partake, He puts the whole fire glowing with love and holiness into our very bosoms, that it may heat us through and through.

He knew that we are at every moment thirsty and faint, and He did not content Himself with calling to us, as Isaias, “all ye who thirst come unto me”, but He placed in the midst of each of us the fountain of living waters springing up unto eternal life.

He knew that we were languid and torpid in all good, and He transfused into our very hearts the principle of life and energy, and all power.

Truly there is in this dealing of God with us an immensity of graciousness, a freeness of communication, such as man’s limited conceptions of goodness never could have reached, and such as will be the wonder and admiration of blessed spirits for all eternity.

Here then we have a daily food, able fully to supply the wear occasioned to the spiritual man by the world and his corrupt nature; and this food no other than the Body and Blood of God’s incarnate Son.
