Consider what privileges you enjoy who have been initiated into the Mysteries, with what company you offer up that mystic hymn, with what company you cry aloud the “Thrice Holy Hymn.” Teach “them that are without” that you have joined the chorus of the Seraphim, that you are ranked as a citizen of the commonwealth above, that you have been enrolled in the choir of angels, that you have conversed with the Lord, that you have been in the company of Christ. If we regulate ourselves in this way we shall not need to say anything when we go out to those who are left behind: but from our advantage they will perceive their own loss and will hasten hither, so as to enjoy the same benefits themselves. For when, merely by the use of their senses, they see the beauty of your soul shining forth, even if they are the most stupid of men, they will become enamored of your goodly appearance. For if corporeal beauty excites those who behold it, much more will symmetry of soul be able to move the spectator and stimulate him to equal zeal. Let us then adorn our inward man, and let us be mindful of the things which are said here when we go out: for there especially is it a proper time to remember them. And just as an athlete displays in the lists the things which he has learned in the training school, even so ought we to display in our transactions in the outside world the things which we have heard here.
