A man making void He brings this comparison from the manner that transgressors were dealt with under the law of Moses, to show how much greater punishments Christians deserve when they are ungrateful to Christ after much greater benefits, when they may be said to have trodden under foot the Son of God by despising him, who was the author of their salvation, by shedding his blood upon the cross. (Witham)
What is here said of the crime of apostacy, may in some measure be applied to every deadly sin committed after baptism or the sacrament of penance; for a Christian by returning to sin, treads under foot the Son of God, despises the adorable blood by which he was sanctified, and offers a henious affront to the spirit of grace. Apostacy, though enormous, like all other sins can be forgiven by true repentance; but the apostle declares, there is no victim for the guilt of a person who perseveres and dies in apostacy.
For, he says, Hebrews 10:28 He that has despised Moses' law dies without mercy, under two or three witnesses. Without mercy, he says; so that there is no pardon, no pity there although the law is of Moses; for he ordained the most of it.
What is under two or three? If two or three bore witness, he means, they immediately suffered punishment.
