4 For if He were on earth, He would not be a priest, since there are priests who offer the gifts according to the law; 5 who serve the copy and shadow of the heavenly things, as Moses was divinely instructed when he was about to make the tabernacle. For He said, “See that you make all things according to the pattern shown you on the mountain.” (Hebrews 8:4–5, NKJV)
Jesus was not a son of Aaron. Being from the tribe of Judah, he could not be a priest according to the law of Moses. That law “had to be changed” for Jesus to “become High Priest forever according to the order of Melchizedek” (Heb. 7:11-14; 6:20). Since the priesthood has indeed changed (Jesus is now High Priest), the law has also changed. The new covenant of Christ is now in force, dispensing redemption and arranging our new life in Christ, including acceptable worship. The old covenant tabernacle worship (offered by the sons of Aaron) served as a copy and shadow of the heavenly things accomplished by our High Priest, Jesus (Heb. 7:24-28). But, even the wilderness tabernacle (the shadow of the “true tabernacle” which is the church, Heb. 8:1-2; 10:21) was built according to God’s revealed pattern. We believe God-given patterns for worship still matters to God (2 Tim. 1:13). The new covenant of Christ contains a pattern of worship to follow (Jno. 4:23-24). We must see that we follow it. What pattern do you follow when you worship? Is it the new covenant pattern, or the commandments of men (Matt. 15:8-9; Col. 1:21-23)?
