Man can be responsible with God's grace
Responsibility > Entrusted to man
In the Middle Ages, responsibility assumed moral relations with reason and virtues.
However, philosophies and religions arose confuting the human possibility of assuming responsibilities, but on this trail, once the individual has no moral relationship with the other, solidarity on good and evil disappears and the restricted concept of responsibility of Cain pervades the works, followed ways, testimony and struggle.
To clarify moral relationships with reason and virtues, St. Thomas wrote that virtuous actions are recommended to men in many ways by the writings of the new testament, by predisposition from the grace of the Holy Spirit; He gives and infuses man with the new law, not only as an indicator of things to do, but also as an aid to accomplish them, with the strength that is needed to live the truth.
