"The true Church of God must be united, fastened and joined together in one same doctrine and belief" Over the last months, we have made the visible unity of the Church's faith a central theme of a number of essays.  In short, the Church is essentially united in her external profession of faith. This is an essential aspect of the property of unity itself. As one of the four notes of the Church recited in the Creed, this unity of faith is a "negative" property in the sense that the true Church of Christ can never lack it. Any society claiming to be the Church of Christ shows itself to be a false claimant if it lacks this unity of faith.
