The document discusses Jesus' words about eating his body and drinking his blood during the Last Supper and the reactions they elicited. It notes that Jesus used metaphoric language to teach spiritual lessons and that there were different types of followers seeking him for various reasons, like signs, prosperity or politics. Some disciples rejected Jesus' difficult teachings and walked away, showing how followers can fall into apostasy. The document contrasts invented religions focused on ceremonies and works with the Bible's teaching of salvation by God's grace alone.
