Arthur Michael Ramsey, in The Glory of God and the Transfiguration of Christ, argues that the Transfiguration is key to understanding the entire Christian mystery, demonstrating the unity of the cross and glory, as well as the relationship between the Old and New Testaments. Ramsey connects the Transfiguration with Jesus' impending death in Jerusalem, where Moses and Elijah 'appeared in glory and spoke of his death'. He sees the Transfiguration as a mirror that unites many important aspects of the Christian faith. Ramsey emphasizes that the cross and glory are one and the same, implying that the glory experienced by Christ is an integral part of his sacrifice.
