Jude 1:3-4

Beloved, while I was very eager to write to you about our common salvation, I was constrained to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints.

For there are certain men who crept in secretly, even they who were of old written of beforehand to this condemnation: ungodly men, turning the grace of our God into lasciviousness, and denying our only Master, God, and Lord, Jesus Christ.
