Jude 1:2-4

Mercy unto you and peace and love be multiplied. Beloved, while I was giving all diligence to write unto you of our common salvation, I was constrained to write unto you exhorting you to contend earnestly for the faith which was once for all delivered unto the saints. For there are certain men crept in privily, even they who were of old written of beforehand unto this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying our only Master and Lord, Jesus Christ.
