Jude asks that “mercy, peace, and love be multiplied” to his readers Jude 1:2. It is a short opening prayer for an increase of these gifts Jude 1:2.
Jude identifies himself as Jesus Christ’s servant and as James’s brother, then addresses a group defined by God’s action toward them: they are called, set apart by God the Father, and kept for Jesus Christ. The greeting front-loads relationship and belonging rather than location or achievements. These lines function as the letter’s opening greeting, doing three things that shape how the rest should be heard. First, the writer names himself and signals a posture of service to Jesus Christ.
Jude opens by identifying himself and the people he is writing to.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Jude 1:2, then read the surrounding section so the answer stays connected to the passage's flow.
