Herman Bavinck said this around 100 years ago – it has to do with justification by faith alone and the imputation of Christ’s righteousness.
“…It is said in Rom. 4:5 and 5:6 that God justifies the ungodly. It is impossible…to use stronger language. The opponents of imputed righteousness should not lodge their objection against Luther and Calvin but against Paul.”
The quote is found in Bavinck’s outstanding discussion of justification: Reformed Dogmatics IV.213.
