According to Thomas Slater, writing in the
Catholic Encyclopedia, reparation is a theological concept closely connected with the concepts of
atonement and
satisfaction. Although God could have chosen to condone the sins of humanity, in
divine providence, he instead judged it better to demand satisfaction through reparation and penance for sins of humanity. In Catholic teaching, it is better for the education of man that wrongdoing on humanity's part should entail the necessity of making satisfaction; this satisfaction was made adequately to God by the suffering,
passion and
death of Jesus Christ. By voluntarily submitting to his passion and death on the cross, Jesus thus atoned for man's disobedience and sin, and made reparation to God for the offenses of humanity. Mankind thus makes reparation to the justice of God for their sins, and by virtue of the
Communion of the Saints, the oneness and solidarity of the mystical
Body of Christ, can also make satisfaction and reparation for the sins of others. Francis extends this idea, proposing "that we develop this means of reparation, which is, in a word, to offer the heart of Christ a new possibility of spreading in this world the flames of his ardent and gracious love": in the acts of fraternal love through which believers heal the wounds of the Church and of the world, ... they offer new ways for the healing power of the heart of Christ to express itself. ==Historical perspective==
