Kids And Discipline

Non coques haedem in lacte martis suae. Haedus hic sub peccatoris figura introducitur. Proinde peccans graviter non est coquendus in lacte matris suae, id est, non est purgandus mediocribus tenerrimisque Ecclesiae disciplinis, sed austerioribus praeceptis ejus sunt excoquenda peccata, cujus magna sunt crimina, ut qui per lasciviae blandimentum se perdidit, fortiori disciplina se redimat. Sanctus Isidorus Hispalensis,Mysticorum Expositiones Sacramentorum Seu Quaestiones In Vetus Testamentum, In Deuteronomium, Caput VIII Migne PL 83.362

Do not cook a kid in his mother's milk. 1 The kid is given here as a figure of the sinner. Whence he who sins gravely should not be cooked in the milk of his mother, because he will not be cleansed with some moderate and tender ecclesiastical discipline, but rather with severe instruction the sins must be boiled out of him, that he who has destroyed himself by lascivious blandishments, by firmer discipline be saved. Saint Isidore of Seville, Expositions of Sacred Mysteries or Questions on the Old Testament, On Deuteronomy, Chap 8 1 Deut 14.21
