Some people believe that clergy who comment on political issues should focus only on worship in their churches and leave social and political matters to politicians. As members of the church, we should be content with prayer and praising God, and if we have any opinions on political or economic issues, it has nothing to do with Christianity.
The problem with this view is that the one God to whom we pray and whom we worship cares about these economic matters: He says He is the God of the poor. He says He is the God of the just, which means He sides with the powerless and oppressed, the widow and the orphan, and stands against their oppressors. The God who meets us in the Bible – and especially in Jesus Christ – tells us that we cannot be with Him, we cannot sincerely worship Him, or speak truthfully about Him if we are not in solidarity with the poor.
