How do we know Christ's holiness is true?

Christ's holiness is foundational to His identity as our Great High Priest. The passage in Exodus 28 vividly illustrates the symbolic nature of the high priest's garments, which represent Christ's personal holiness. He is portrayed as a being who never sinned and had no inclination towards sin, thus fulfilling the requirement for a perfect sacrifice. This holiness is not just a characteristic; it is His very nature as the Son of God, inherently holy and separate from sinners, making Him uniquely qualified to intercede for us and bear our iniquities.
