"Christ can be admired as an aesthetic genius, the greatest ethicist, as one going to a heroic death for His ideals. Only this doesn't bring the center of ourselves into contact with the focal claim of Christ to speak the revelation of God and to be that revelation. Through such deflection, a great distance is maintained between us and the Word of Christ, and no true encounter can take place.
I can no doubt live without an ethical or religious Jesus in the same way I can live without Kant or Plato, but should there be something in Christ which claims my life entirely with the full weight that God Himself indeed speaks here, once made present in Him, then Christ has not only relative but absolute, urgent significance for me.
Understanding Christ means taking this seriously. We must release this truth from the folly of the times - the secular and the modernal - and see Christ as He seeks to be seen".
Dietrich Bonhoeffer - The Essence of Christianity.
