Romans 6:10

Jesus Christ will never have to die again because when He died for sin He died to sin. This means that when He died His relationship to sin changed. It was never the same again. Sin now has no power over Him. After He paid for our sins, He was free to resume His intimate relationship with God forever.

"This stands in opposition to the doctrine and practice of the so-called perpetual sacrifice of Christ in the Roman Catholic Mass." [Note: Witmer, p. 463. Cf. Hebrews 7:27; 9:12; 10:10.]
