Bonaventure — on 1Cor 7:2 (Disputed Questions on Evangelical Perfection, Question 3)

“Against the vowing of widowed continence it is objected: 1 Corinthians 7: On account of fornication let each man have his own wife, and each woman her own husband: but that is not a counsel, since it is not a work of perfection nor of supererogation: therefore it is a precept: therefore whoever vows continence acts against this precept.”
