I have written anything erroneous concerning this
sacrament or other matters, I submit all to the judgment and correction of the Holy Roman Church, in
whose obedience I now pass from this life.
St. Thomas Aquinas, perhaps the greatest Catholic
theologian and Church Doctor since St. Augustine, was noted for his holiness of
life even in his childhood years. This great Christian philosopher is most
famous for his doctrinal work, Summa Theologica, which
includes writings on the Incarnation, the Trinity,
the Angels, Creation, Grace, Increases in Grace, the Seven Sacraments, the
Saving Effects of Baptism, Penance, Mortal Sin, Confession, the Real Presence
of Christ in the Eucharist, the Importance of Confirmation, What Must Happen after a person
loses grace before grace can be restored, etc.
