But the victory – let us repeat it again and again – has been achieved on the Cross; and His Cross is not only the supreme revelation of the boundless condescending Love of God, but also the center, the backbone and pivot of our own new life. We enter this new life only by participating in the Cross of Christ, crucifying thereon our “old Adam” and partaking in the perfect obedience of Christ.
Christianity is therefore much more than a message: it is a new reality, a new life, a painful and courageous transfiguration of the old man into the “new creature,” into a “member of the body of Christ.” “The old things have passed away. Behold! Everything has become new!” It is a promise and a beginning of – let us repeat it – a New Reality, already revealed and given to us in the coming, the death and the resurrection of Christ, which are the “leaven” of the new order of being. This leaven has to permeate the whole lump. (Nicholas Arseniev, Revelation of Life Eternal, p. 87)
