“Faith is the beginning of happiness in the mind. It is even more than this. Because faith proposes to man the possibility of attaining the vision of God, it gives man the beginning of happiness in his heart. Faith then lays the foundation of hope in the heart of man.”
(Walter Farrell, O.P., S.T.M. and Martin J. Healy, S.T.D., My Way of Life: Pocket Edition of Saint Thomas, The Summa Simplified for Everyone, p. 333)
