Roman Catechism 14.26

Chapter 14 — Part I: The Creed — Article XII: Life Everlasting

Section 26. Peace — To enumerate all the delights with which the souls of the blessed shall be filled would be an endless task. We cannot even conceive them in thought. With this truth, however, the minds of the faithful should be deeply impressed -- that the happiness of the Saints is full to overflowing of all those pleasures which can be enjoyed or even desired in this life, whether they regard the powers of the mind or of the perfection of the body; albeit this must be in a manner more exalted than, to use the Apostle's words, eye hath seen, ear heard, or the heart of man conceived.
