D.S. Warner emphasizes the divine origin and essential attributes of the Primitive Church, highlighting its divinity, organization, visibility, oneness, unity, and holiness. He argues that the church is a living entity, built by Christ and governed by divine principles, and that it must remain united under one name, the Church of God, to fulfill its mission. Warner stresses that divisions among believers are contrary to the teachings of Christ and that true unity is achieved through sanctification and adherence to the Word of God. He calls for a return to the original, unblemished state of the church as intended by God, free from human-made sects and divisions.
