How does God define the church? What comprises it according to the Bible? The ekklesia, the Greek word translated "church" in the Bible, is not a humanly defined corporation, but the mystical body of Christ, having the Spirit of God. The true church of God is an invisible, spiritual organism, of those people that have and are led by the Spirit of God. And such a person will not turn away from the teaching delivered by the apostles.
John Ritenbaugh reiterates that a recurring pattern God uses is to set apart one group of people to become a blessing to the rest of the world by keeping His covenant, providing a good example. Ancient Israel was asked to purge the land of Gentile customs and practices. In the New Testament, the church (the Israel of God) was asked to come out of the world, having as little contact as possible with its political, educational, and social institutions (with its unseen spiritual influences). Like Nehemiah, our worldview has to stem from a fear of God. Adopting the world's standards automatically makes one an enemy of God. Our enemy is not the people of the world, but the subtle satanic spiritual influences that determine their attitudes and values. Our intimate fellowship should not be with the world, but be concentrated upon God and those who have made the Covenant with God, loving them as we would ourselves.
In this sermon on the meaning of Unleavened Bread, John Ritenbaugh warns that emphasizing our initiative at putting out sin is wrong. Unleavened bread serves as a memorial of God's initiative of delivering us from the bondage of sin. Like our forebears, we have to realize that our part of the salvation process is to follow God's lead, cooperating with His will. When we metaphorically leave Egypt (a type of the world), we leave the location of our sin, leaving behind anything that will hinder us from reaching the Promised Land. Eating unleavened bread symbolizes following God's lead, doing righteousness, and imitating the righteousness of God.
John Ritenbaugh observes that ancient Israel had at the core of its religion (as well as its dominant cultural norm) an obsession to serve or please the self at the expense of justice and truth and the best interests of the socially disadvantaged. Because of Israel's excessive self-seeking and self-serving pride, God threatens to remove His protection, allowing its people to go into captivity. Pride (the catalyst for Laodiceanism) causes people to reject God and to follow idolatrous ways. Israel's leaders should 1) never be content with the way things are, 2) never let care and concern for self take priority over the welfare of others, 3) covet peace with God, but only on His terms, 4) choose things that are more excellent, and 5) embrace morality.
