In the words of Jean Vanier, "Grace should always perfect our nature...it should make us more human, not take away our humanity." In claiming this, I suggest, what Vanier does is to help establish a Spirituality of the cross. I am taking this distinction from Luther who worried about a theology of glory, and suggested, in contrast, a theology of the cross. I think the same can apply to Spirituality. Grace, therefore, does not simply orient us to heaven, where we now turn our attention away from the world and on to glory - far from it - grace, and through it, true humanity, is tied to Jesus' life. Jesus is the true vision of humanity - humanity at its highest perfection. It is true that one day we will know of another kind of perfection, but that is not available to us this side of glory. We are pilgrims, albeit justified and sanctified pilgrims, we are pilgrims nonetheless.
Spiritual formation therefore, if it is to be truly Christ-oriented, must understanding grace as perfecting us in such a way that we become like Christ. We do not become like Christ in his glorified body, not yet. In this side of glory, we become like Christ as he proclaimed the kingdom of God, as he ministered to the broken, needy and hungry, and as he understood his specific calling and oriented his life around that. A Spirituality of the cross necessitates seeing the cross as the ultimate shape of life. Our leadership plans, church services and formation theology should be conformed to Jesus and the organic message of true Spiritual, and therefore cruciform, growth, rather than the wordly counterpart of success, winning and vision.
"Sanctification does not signal the birth of self-sufficiency, rather it indicates a 'perpetual and inherent lack of self-sufficiency'. Sanctification 'in' the Spirit is not the Spirit's immanence in the saint. Quite the opposite: it is a matter of the externality of sanctitas christiana, the saint being and acting in another. 'Sanctification in the Spirit' means: it is not I who live, but Christ who lives in me. And 'Christ lives in me' means: by the Spirit's power I am separated from self-caused self-destruction, and given a new holy self, enclosed by, and wholly referred to, the new Adam in whom I am and in whom I act."(Webster, Holiness 83-84)
