Christians are not just called to be transformed into something better or even good, but to be transfigured into a new creation–ceasing to be what they are in order to become what they are not. In The Eucharist’s Biographer, Albert Walsh proposes that the path to this distinctive Christian identity is through the power of the Holy Spirit, as revealed in the unity of Word and Sacrament. With this premise, he unites two powerful traditions: the Proclamation of the Word of the Protestant tradition and the Power of God’s Grace in the Eucharist of the Roman Catholic and Eastern Orthodox traditions. It is in what Walsh calls the eucharistic-evangel as a whole that the individual and community are subject to the real presence of the Christ, who, in the power of the Holy Spirit, is the force behind the transformation and maintenance of Christian identity.
