"Critical Loyalty" - which may seem like a contradiction at first glance - characterizes the work of Theodor Schneider: He remains loyal to the Roman Catholic teaching tradition while critically engaging with developments in theology, the church, and society in the best sense. Content-rich yet expressed in accessible language, he articulates how topics in systematic theology can be convincingly explained, taught, and most importantly, lived today. This book compiles enduringly relevant texts by Theodor Schneider, covering themes that span the spectrum of dogmatic treatises: the transmission of faith, God's revelation, the confession of Christ, spiritual experiences, the church as a place of salvation, the scandal of division, signs of God's closeness, and the promised future.
