Another reason Christians these days cannot allow the church to be fully identified with any particular party is the problem of what the British ethicist James Mumford calls “package-deal ethics.” Increasingly, political parties insist that you cannot work on one issue with them if you don’t embrace all of their approved positions.
This emphasis on package deals puts pressure on Christians in politics. For example, following both the Bible and the early church, Christians should be committed to racial justice and the poor, but also to the understanding that sex is only for marriage and for nurturing family. One of those views seems liberal and the other looks oppressively conservative. The historical Christian positions on social issues do not fit into contemporary political alignments.
So Christians are pushed toward two main options. One is to withdraw and try to be apolitical. The second is to assimilate and fully adopt one party’s whole package in order to have your place at the table. Neither of these options is valid. In the Good Samaritan parable told in the Gospel of Luke, Jesus points us to a man risking his life to give material help to someone of a different race and religion. Jesus forbids us to withhold help from our neighbors, and this will inevitably require that we participate in political processes. If we experience exclusion and even persecution for doing so, we are assured that God is with us (Matthew 5:10-11) and that some will still see our “good deeds and glorify God” (1 Peter 2:11-12). If we are only offensive or only attractive to the world and not both, we can be sure we are failing to live as we ought.
