Faith entails transformation

"Thus the trinitarian dogma proposes a model of personal being which radically challenges the assumptions of the fallen human mind: thought itself must be turned upside down by grace if we are to grasp the mystery in any way. The dogma is a 'cross for human ways of thought' because it demands a belief that the abnegation of self and the absence of self-asserted, self-interested 'individualism' are the fundamental notes of personal existence at its source, in God. In its fallen and encapsulated condition, the individual human subject cannot accept this: only in the life of the Spirit, who transforms the whole of human being, is faith in the trinitarian dogma possible."

+Archbishop Rowan Williams

It is by way of the Spirit, that Christ has bestowed upon us in His Church, that our minds must be renewed so that we can see into the depth of things, the gift of the new creation.
