The Lord Jesus Christ, in His great high priestly prayer, declared clearly the truth of God’s Word. He said, “Sanctify them through thy truth: thy word is truth.” God’s Word not only contains the truth but rather it is truth itself. The Lord Himself therefore identified truth with the Written Word. There is no source, other than written Scripture alone, to which the statement, “thy word is truth” can apply. This in contrast to the tradition of the Roman Catholic Church.
