For three years He went about doing good, giving sight to the blind, hearing to the deaf, healing all kinds of diseases, raising the dead to life, and preaching throughout Judea the new Gospel of peace.6 On Good Friday He was crucified on Mount Calvary, and thus purchased for us redemption by His death. Hence Jesus exclusively bears the titles of Savior and Redeemer, because "there is no other name under heaven given to men whereby we must be saved."7 "He was wounded for our iniquities; He was bruised for our sins, ... and by His bruises we are healed."8 We are commanded by Jesus, suffering and dying for us, to imitate Him by the crucifixion of our flesh, and by acts of daily mortification. "If anyone," He says, "will come after Me, let him deny himself, and take up his cross daily and follow Me."9 Hence we abstain from the use of flesh meat on Friday — the day consecrated to our Savior's sufferings — not because the eating of flesh meat is sinful in itself, but as an act of salutary mortification. Loving children would be prompted by filial tenderness to commemorate the anniversary of their father's death rather by prayer and fasting than by feasting. Even so we abstain on Fridays from flesh meat that we may in a small measure testify our practical sympathy for our dear Lord by the mortification of our body, endeavoring, like St. Paul, "to bear about in our body the mortification of Jesus, that the life also of [003] Jesus may be made manifest in our bodies."10 The Cross is held in the highest reverence by Catholics, because it was the instrument of our Savior's crucifixion.
