The premise is troubling, but I don't blame Doritos or Pepsi. Why would we expect any less from corporations for whom the bottom line is their bottom line? Besides, it's pretty much the image of many evangelical churches and institutions: do whatever we can to get people in the building (free cable, anyone?). Conversely, it's the image of evangelicals themselves: I'm going to go wherever "I'm fed" and to whomever will entertain me the most. We are indeed consumers.
Jesus said to them, ‘For real, people, I'm telling you, you are searching for me, not because you want something great to happen in your life, but because you want me to fill your bellies. (John 6:26, JDSV)And while food & drink is indeed a foundational image that Jesus used heavily, the one depicted here and in much of the evangelical church's emphasis on "more" is far from the picture Jesus gives us in John 6, just after having filled the bellies of some five thousand people on a hillside (feel free to read the whole chapter for context). While "feeding the flock" is indeed our job, the bread and the cup that Christ offers, and thus the Church should offer, is one that is otherwise difficult to accept:
So Jesus said to them, ‘Very truly, I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Those who eat my flesh and drink my blood have eternal life, and I will raise them up on the last day; for my flesh is true food and my blood is true drink. Those who eat my flesh and drink my blood abide in me, and I in them. Just as the living Father sent me, and I live because of the Father, so whoever eats me will live because of me. This is the bread that came down from heaven, not like that which your ancestors ate, and they died. But the one who eats this bread will live for ever.’Doritos and Pepsi are easy to consume. So is "Jesus will make your life just swell." But it's hardly the message of the good news.
When many of his disciples heard it, they said, ‘This teaching is difficult; who can accept it?’ (John 6:52-60, NRSV)
