Signs of Belonging: Lutheran Voices

Signs of Belonging: Luther's Marks of the Church and the Christian Life explores Luther's teaching on the seven marks of the church: possession of the Word, Baptism, Sacrament of the Altar, Office of the Keys, Office of Ministry, Discipleship, and the cross (suffering on account of one's faith). How do these marks define the corporate body of Christ and connect with the lives of individual Christians?
