The suffering that food animals undergo, the suffering of those who eat them and profit by them, the suffering of starving people who could be fed with the grain that feeds these animals, and the suffering we thoughtlessly impose on the ecosystem, other creatures, and future generations are all interconnected. It is this interconnectedness of suffering, and its reverse, of love, caring, and awareness, that calls out for our understanding.
Jesus tells us what the 'protocol' is, on which we will be judged. It is the one we read in chapter 25 of Matthew's Gospel: I was hungry, I was thirsty, I was in prison, I was sick, I was naked and you helped me, clothed me, visited me, took care of me. Whenever we do this to one of our brothers, we do this to Jesus. Caring for our neighbor; for those who are poor, who suffer in body and in soul, for those who are in need. This is the touchstone.
As long as we are on firm moral ground, as long as we're caring about other people, these are legitimate worries. The minute that we start protecting our own interests in the name of these worries and saying, "Oh, we have to make sure that only Ford Motor Company manufactures cars, because we can't be sure that the cars in other countries are being made quite up to our point of view," we're economically off base, and, of course, we're moral hypocrites, too.
What you do in the present—by painting, preaching, singing, sewing, praying, teaching, building hospitals, digging wells, campaigning for justice, writing poems, caring for the needy, loving your neighbor as yourself—will last into God’s future. These activities are not simply ways of making the present life a little less beastly, a little more bearable, until the day when we leave it behind altogether. They are part of what we may call building for God’s kingdom.
