"As John preceded Christ, so the gospel precedes the mass."

"The church has decided that the mass must not be celebrated without the reading of the gospel. Therefore God has placed greater importance on the gospel than on the mass, for without the gospel man does not live in the Spirit, but he does without the mass. 'For man shall live by every word that proceeds from the mouth of God' [Cf. Matt. 4:4], as the Lord himself teaches at greater length in the sixth chapter of John. The mass then renews those who are already a part of the body of Christ, but the gospel, the sword of the Spirit, devours the flesh, divides the kingdom of the devil, takes away the possessions of the strong and increases the body of the church. The mass helps only those who have life; the gospel, on the other hand, helps everybody. Hence, in the early church, the demoniacs and catechumens were permitted to remain until after the reading of the gospel and only then were dismissed by those who were permitted to eat and drink of the body of Christ in the mass. Even now church law permits those who have been excommunicated to remain at the mass until after the reading of the gospel . As John preceded Christ, so the gospel precedes the mass. The gospel prostrates and humbles, whereas the mass conveys grace to those who are humbled. Therefore it would be better if they forbade the mass [rather than silence the gospel]."
