4 For we, the ministers of Christ, have admitted every one, and occupying, as it were, the place of door-keepers we left the door open: and possibly thou entered with your soul bemired with sins, and with a will defiled. You entered, and were allowed: your name was inscribed. Tell me, do you behold this venerable constitution of the Church? Do you view her order and discipline, the reading of Scriptures, the presence of the ordained, the course of instruction? Be abashed at the place, and be taught by what you see. Go out opportunely now, and enter most opportunely tomorrow.
If the fashion of your soul is avarice, put on another fashion and come in. Put off your former fashion, cloke it not up. Put off, I pray you, fornication and uncleanness, and put on the brightest robe of chastity. This charge I give you, before Jesus the Bridegroom of souls come in and see their fashions. A long notice is allowed you; you have forty days for repentance: you have full opportunity both to put off, and wash, and to put on and enter. But if you persist in an evil purpose, the speaker is blameless, but you must not look for the grace: for the water will receive, but the Spirit will not accept you. If any one is conscious of his wound, let him take the salve; if any has fallen, let him arise. Let there be no Simon among you, no hypocrisy, no idle curiosity about the matter.
