Ephesians 5:12

For the things which are done by them in secret it is a shame even to speak of.

Although this verse is surely true of all wicked men, MacKnight, and others, have detected a close connection here with the various mystery cults of paganism. His paraphrase of Ephesians 5:11-12 brings this out thus:

And have no fellowship with those who celebrate the heathen mysteries, which being transacted in the darkness of night are really the unfruitful works of darkness, as they bring no fruit to the initiated, except eternal death: But rather reprove them. For the impure and wicked actions which are secretly done in the mysteries by the initiated, are so abominable, that it is base even to mention them.[11]
