The three theological virtues of faith, hope, and charity are given by God to those who are in a state of grace. Regarding the theological virtues St. Thomas Aquinas states, “the theological virtues direct man to supernatural happiness in the same way as by the natural inclination man is directed to his connatural end” (STII, Q62, A3). The three virtues are different, but linked together in purpose, function, and motive.
The author of the letter to the Hebrews described faith as something hoped for. We see this in Hebrews 11:1 where the author states, “Now faith is the assurance of things hoped for, the conviction of things not seen” (NRSV). Faith is the basis on which our hopes are founded and is the basis of merit (Hardon Ch. 10). Through faith we do not believe in fanciful myths or new theologies because we know what has been revealed, and to whom it has been entrusted.
Hope is related to faith because faith spurs hope. Furthermore, hope looks to the object of our faith. The object of our faith is supernatural, and hope helps us to attain supernatural truth. It shows us what to strive for and implies a modicum of pursuit. Are we pursuing the truth of God, or are we pursuing temporal things? If temporal, then we hope to attain them through our own efforts. If supernatural, thee is no way possible to attain them on our own. This is the error of Pelagianism that was condemned in the early days of the church. It is only through the revelation and assistance of God that we may achieve this end.
Charity, as is hope, is something that is directed to and fulfilled by the Almighty (Hardon Ch. 10). Hope is self-serving in a way because it is and end that we hope for ourselves, but charity is different. Charity comes about when we love God for who he is instead of what we can attain through Him. When we love God with everything we have we then seek to love him the way he wishes to be loved.
Faith, hope, and charity have their beginning and end in God. Faith is the substance of things hope for. Hope looks to God who is the object of our faith. In Charity we seek to love God the way he wishes us to love, and that includes loving him above all things and loving our neighbor. It is in this way that the three are distinct but intrinsically connected.
