Everyone knows, beloved brethren, that it is impossible for a Christian and, in a special way, a priest, to imitate the admirable example of the Divine Master in daily life without the help of grace, and without the use of those instruments of grace which He Himself has placed at our disposal: a use which is as much more necessary as the grade of perfection to which we are bound to attain is higher, and as the difficulties which arise from our natural inclination to evil are greater. For this reason, We judge it opportune to pass on to the consideration of certain other truths, as sublime as they are consoling, from which should appear still more clearly how deep should be the sanctity of the priest, and how efficacious are the helps given to us by the Lord to enable us to fulfill in ourselves the designs of His divine mercy.
