The Letter of Jude ~ Jude 1 vs. 4: For certain persons have crept in unnoticed, those who were long beforehand marked out for this conndemnation, ungodly persons who turn the grace of our God into licentiousness and deny our only Master and Lord, Jesus Christ.

Footnote: deny our only Master and Lord, Jesus Christ. The Greek word here for "Master" may be translated "despot" (cf. Acts 4:24, 1 Tim: 6:1) and is applied here to Jesus. To deny Jesus as Lord was to disbelieve the most basic Christian tenet.
