My soul-bond with the Eucharist -- the body of Christ -- has consoled me in my darkest hours of degenerative disease and disability.
The body of Christ draws me ever nearer to Him; it unites me with His suffering, death, and the assurance of future eternal glory in the resurrection, of which Christ is the first fruits. It is the real presence of my Lord, body and blood, together with His soul and divinity. "The whole Christ is truly, really and substantially contained" in the Eucharist.
