ERROR MUST BE REFUTED!
Jude, In his short epistle to Christians, warns of God's judgment that will fall upon apostate Christians. Even then, ungodly men had crept into the church and were turning the grace of God into lasciviousness. Jude writes:
"Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints." Jude 1:3
The faith which was once delivered unto the saints was the obedience of faith. The obedience of faith was the gospel that Paul preached:
"Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began, But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:" Romans 16:25-26
