To the Churches:
The presence of people at church for worship should be the most sanctified gathering we experience this side of heaven. At the very heart of worship is the acknowledgment and attributing of God's worthiness to him as God. There should be no secondary or other focus of our worship. Anything that falls outside of pure reverence for God should be questioned sternly.
Now there are many things that become questionable in worship if we are to take worship as seriously as the Christian faith warrants. Accordingly, the presence of any politician for political gain at a worship service is first and foremost a neglect for the God that we should be gathering to worship. No matter how 'religious' the politician may be or claim to be, there is no place in worship for stumping, as Jared Bridges soundly defends.
Politicians should absolutely be welcomed when attending our churches, just as every other person. There would even seemingly be no problem with a politician holding an office in the church so long as the person met the biblical qualifications for the position. However, allowing a mortal man or woman the platform to advance their political views and allow such a presentation to become mixed with the church's gathering to worship an Almighty God is completely and utterly deplorable. How can any church stand for such a shameful distraction?
As the news has covered politicians speaking lately in churches trying to gather last-minute votes I feel like the church is being prostituted to the world. When a church becomes no more than a social organization that invites politicians to come and address its members (even in a non-partisan "both sides" event) the church has ceased to be the church. For whatever purpose these people are gathering, it is not to be the church nor to worship God.
Believers in Christ should be informed voters. Believers in Christ should be active in our country's political system. However, the worship service is neither the time nor the place for a political speaker or a political rally to take place.
Every church certainly falls short of worshiping in the most biblical way that we are able. Many things could and should be changed to make our worship more God-centered and less man-centered. The church that would claim to have everything perfectly in order would surely be sinful in such a claim. This matter is not one for a church to boast over another church. Rather, it is a pressing matter for us to examine ourselves and to seek to be more biblical churches in the future than the present.
