Contradiction with Hebrews 10:1
Hebrews 10:1 states that the law is a shadow of good things to come and not the very image, suggesting the law's imagery fails to perfect, contradicting Hebrews 7:28's notion of the law appointing weak high priests.
Hebrews 10:1: For the law having a shadow of good things to come, [and] not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
Contradiction with Hebrews 9:11
This verse speaks of Christ being a high priest of good things to come by a greater and more perfect tabernacle, contrasting with Hebrews 7:28, which emphasizes the appointment of human high priests under the law.
Hebrews 9:11: But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building;
Contradiction with Romans 8:3
Romans 8:3 implies that the law was unable to bring salvation due to its weakness through the flesh, while Hebrews 7:28 mentions the law appointing men with infirmities, suggesting a focus on human frailty.
Romans 8:3: For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: [for sin: or, by a sacrifice for sin]
Paradox #1
Hebrews 7:28 could be seen as contradicting earlier laws about priesthood since it contrasts the law's appointment of imperfect high priests with God appointing a perfect Son. The inconsistency may arise in understanding why the earlier system was flawed if it was part of God's plan.
Paradox #2
Hebrews 7:28 suggests a contradiction by highlighting the difference between the imperfect nature of human priests who were appointed under the law and the perfect nature of Jesus as a priest appointed by an oath. The conflict arises because it seems to contrast human fallibility with divine perfection, raising questions about why an imperfect system was initially established if a perfect solution was available all along.
