And by that will we have been sanctified through the offering of the body of Jesus Christ once for all. (Hebrews 10:10)
“What, then, will we say of those who come forward and pretend that they perpetually present the body of Christ in the unbloody sacrifice of the mass? We say that no profane jest from the lip of Voltaire ever had even the slightest degree of God-defiant blasphemy in it compared with the hideous insult of this horrible pretense. It is infernal. There can be nothing more intolerable than the notion, for our Lord Jesus Christ has offered Himself for sin once, and once for all; and he who dares to think of offering Him again, insults Him by acting as if that once were not enough. There would be no language of abhorrence too strong if the performers and attendants at the mass really knew what is implied in their professed act and deed. In the judgment of Christian charity we may earnestly pray, “Father, forgive them; for they know not what they do” (Luke 23:34).
