22 And God placed all things under [Christ’s] feet and appointed him to be head over everything for the church, 23 which is his body, the fullness of him who fills everything in every way.
Since Christ fills everything, and the church is the fullness of him, then there can be no separation of church and state. I think the church is symbolic, in this passage, of all Christians, not a certain denomination. So Christians, according to the Bible, should not have to separate their views from their job, schooling, or politics. This is because they, in Christ, fill everything in every way. Therefore, in contrast, their views should soak their job, schooling and politics.
