Bread suggests togetherness, care and love, hopes and dreams, fun and adventure. 

Let's say some new friends invite you to their house for a meal. When you are a guest in their home, they are sharing their intimacy with you. They are sharing with you some of the privacy of that place where they live every day, eat every day, love every day, work on their problems, argue from time to time, sleep and depart for work and pleasure and return for rest, every day.  

After graciously receiving you, they show you around their home in which they take deep pride. Then you go to the dining room for the meal. You find the table set with care, the food exceptionally delicious, and the conversation flows easily. Simply put, it becomes a lovely evening and you leave feeling full in every way. You enjoy bread from the kitchen, but much more. You enjoy the bread of being graciously received, the bread of informed and lively conversation, and the bread of being in beautiful surroundings.. 

Magnify that thousands of times and you begin to have a glimmer of what the church perceives the Holy Eucharist to be. In the Eucharist Jesus and "Bread of Life" are one. In the Eucharist bread and wine are the elements that nurture faith in God.
