Snake Sandwich and Bird Salad

Commenting on the Acts 11 vision in which Peter is challenged to take a different view as to what is OK and what is not, particularly in respect to food consumption, Walter Brueggemann suggests that it as though Peter hears God saying, "Have a snake sandwich and a bird salad" (Walter Brueggemann, 'Inscibing the Text', Fortress, 2004, p. 88). The point is that the ritual law said that these things were unclean and should not be consumed. Peter, however, has had a vision which suggests he might eat anything. There are times when God takes us in different and unexpected directions. We, too, can be the subject of a vision which shakes us to the very core. We tend to think we know where we should be heading. This story is a reminder not to take that for granted. Does God have different ideas for how we should do and be church? If so, are we ready to see the vision?
