1 Rejoice, you heavens, and let the earth be glad, for those who are to be sprinkled with hyssop, and cleansed with the spiritual hyssop, the power of Him to whom at His Passion drink was offered on hyssop and a reed. And while the Heavenly Powers rejoice, let the souls that are to be united to the spiritual Bridegroom make themselves ready. For the voice is heard of one crying in the wilderness, Prepare the way of the Lord. For this is no light matter, no ordinary and indiscriminate union according to the flesh, but the All-searching Spirit's election according to faith. For the inter-marriages and contracts of the world are not made altogether with judgment: but wherever there is wealth or beauty, there the bridegroom speedily approves: but here it is not beauty of person, but the soul's clear conscience; not the condemned Mammon, but the wealth of the soul in godliness.
