The catalog

Build on the rock. One hard question of the faith, trusted voices across the Church’s traditions — kinship and honest difference. Editions prepared for deep reading.

Two questions, eight voices: How does the believer put sin to death? and How does Scripture hold the Church in one faith?

Tertullian

Short classic · often where groups start
