St. Maria Goretti… died at age 12, after forgiving the man who had assaulted her.
St. Maximilian Kolbe… who died in a Nazi Concentration Camp. He volunteered to take the place of another prisoner, sentanced to death. And in a way, because of St. Maximilian’s heroic Christian Charity… that prisoner received “forgiveness”… of his death penalty (even though, it was unjustly inflicted by evil men).
And of course, the primary example… is Our dear Lord, Himself. As He forgave those who were torturing Him… and putting Him to death.
“And Jesus said, ‘Father, forgive them, for they do not know what they are doing’.” (Luke 23:34)
God bless.
