A frequent misinterpretation of Hebrews 10:21 is viewing the 'high priest' as endorsing a continuing human priesthood or hierarchical church authority that mediates between God and believers, which contradicts the passage's emphasis on Christ's unique, eternal priesthood that eliminates the need for any human intermediary and grants all believers direct boldness to approach God.
Hebrews 10:21
King James Version (1769)
21 And having an high priest over the house of God;
Hebrews 10:21 underscores the core truth that believers in Christ possess a superior High Priest, Jesus, who reigns over the household of God, providing confident access into God's presence through His atoning work, in contrast to the temporary and restricted access under the old covenant where only the earthly high priest could enter the Most Holy Place annually.
