Those who desire to make a good showing in the flesh try to compel you to be circumcised, simply so that they will not be persecuted for the cross of Christ. For those who are circumcised do not even keep the Law themselves, but they desire to have you circumcised so that they may boast in your flesh. (Galatians 6:12, 13)
Sin is not what Reformed men do. Everyone knows that. It seems stupid to say it. Reformed men have enough money and class to keep their hands clean. We're scrupulous and the worst we can be accused of is not yet having attained the vocabluary necessary to be proficient at teaching doctors, lawyers, engineers, pharmacists, professors, architects and their husbands in our churches' adult discipleship programs. Maybe occasionally bad doctrine seeps in, but never bad practice and never ever bad motives which led to that bad practice. And don't you ever forget it!
It's not simply David-and-Bathsheba-pregnancy-and-murder public sins which have left the earth on UFOs. We don't even sin privately and we can't remember the last time we had to examine our hearts. All our motives are pure--that one you had better get. Don't ever make the mistake of questioning a Reformed man's motives or you'll pay for it; especially if he's an elder or pastor. "How dare you question my motives! What gives you the right? Who are you to talk? Judge not lest you be judged!"
Then his fellow presbyters chime in...
