The Imitation of Christ, by Thomas a Kempis, tr. by William Benham [1886], at sacred-texts.com
Come unto Me, all ye that labour and are heavy laden, and I will refresh you,(1) saith the Lord. The bread that I will give is My flesh which I give for the life of the world.(2) Take, eat: this is My Body, which is given for you; this do in remembrance of Me.(3) He that eateth My flesh and drinketh My blood dwelleth in Me and I in him. The words that I speak unto you, they are spirit, and they are life.(4)
