The document appears to be a call to worship service. It includes hymns, scripture readings, and a sermon on whether it matters what churches teach, believe, how they worship, and how people are saved. The sermon argues that it does matter based on warnings in the Bible about false teachings and the need to follow God's prescribed way of worship and salvation. It cautions against ideas that all churches are equal or that the way to heaven does not matter, citing biblical examples of the importance of correct doctrine and practice.
