Catena Aurea · Matthäusevangelium 2
When they saw the star, they rejoiced with exceeding great joy. And when they were come into the house, they saw the young Child with Mary His mother, and fell down, and worshipped Him: and when they had opened their treasures, they presented unto Him gifts; gold, and frankincense, and myrrh.
(Anselm.) The three men who offer, signify the nations who come from the three quarters of the earth. They open their treasures, i. e. manifest the faith of their hearts by confession. Rightly in the house, teaching that we should not vain-gloriously display the treasure of a good conscience. They bring three (vid. sup. note g, p. 18.) gifts, i. e. the faith in the Holy Trinity. Or opening the stores of Scripture, they offer its threefold sense, historical, moral, and allegorical; or Logic, Physic, and Ethics, making them all serve the faith.
