Ephesians 5 (v)

Avarice, prostitution and immorality are great and terrible sins and our Lord God punishes them with plagues and shortages (...). But the sin is not adultery and whoring, indeed it is not a human sin, but, more than that, it is diabolical that people despise, ridicule and mock the great grace of the fatherly visitation of God on earth. Punishment will certainly follow from that kind of sin, and who can offer any help to those who are not only weak but who trample underfoot those who would lead them? It is simply more than enough that we are sinners but, in addition, we want to slay the person Who would bear with us and bring us to salvation, in other words, our Lord Jesus Christ. Only the irksome Devil does this sort of thing together with those who are full of devils.
