What is understood from this day's gospel, the Good Samaritan,  in a higher and more spiritual sense?

According to the interpretation of the Fathers, our father Adam, and hence the whole human race is to be understood by the one who had fallen among robbers. The human race, which through the disobedience of Adam fell into the power of Satan and his angels, was robbed of original justice and the grace of God, and moreover, was wounded and weakened in all the powers of the soul by evil concupiscence. The priest and The Levite who represent the Old Law, would not and could not repair this misfortune; but Christ, the true Samaritan, embraced the interests of the wounded man, inasmuch as He poured the oil of His grace, and the wine of His blood into the wounds of man's soul, and thus healed him, and inasmuch as He led him by baptism into the inn of His Church, and there entrusted him to His priests for further care and nursing. Thank Christ, the good Samaritan, for this great love and care for you, and endeavor to make good use of His blessings by your cooperation.
