The Certitude of Faith According to St. Thomas Aquinas

According to St. Thomas Aquinas, the certitude of faith is caused by the First Truth which is an object of faith. The question of the certitude was overlooked and the signification of the First Truth was underestimated in the thomist treatises on faith. In my paper, I concentrate on the First Truth as the last perfection of the intellect and the last end of the will. The relationship of the First Truth to the intellect and to the will is fundamental for understanding of the significance of faith's certitude.
