Chapter 14 — Part I: The Creed — Article XII: Life Everlasting
Section 12. The Positive — As for the glory of the blessed, it shall be without measure, and the kinds of their solid joys and pleasures without number. Since our minds cannot grasp the greatness of this glory, nor can it possibly enter into our souls, it is necessary for us to enter into it, that is, into the joy of the Lord, so that immersed therein we may completely satisfy the longing of our hearts.
