Roman Catechism 24.32

Chapter 24 — Part III: The Decalogue — The First Commandment

Section 32. They Do Not Forbid Images Of Christ And The Saints — But to make and honour the images of Christ our Lord, of His holy and virginal Mother, and of the Saints, all of whom were clothed with human nature and appeared in human form, is not only not forbidden by this Commandment, but has always been deemed a holy practice and a most sure indication of gratitude. This position is confirmed by the monuments of the Apostolic age, the General Councils of the Church, and the writings of so many among the Fathers, eminent alike for sanctity and learning, all of whom are of one accord upon the subject.
