Commonground
Christian to Christian, Scripture open. We start with what we already share, then take the big questions one at a time, in the Church’s own words: Mary, the saints, the Pope, the Bible and Tradition, and more.

Your verse first
Common questions from Protestant Christians: your verse first, then the Catholic reading, then where we think the disagreement lies.
- Isn’t Scripture alone enough?
- Wasn’t the papacy invented centuries later?
- If there is one mediator, why ask saints to pray?
- Where is purgatory in the Bible?
- Why does the Catholic Bible have extra books?
- Aren’t statues and icons forbidden images?
- If Christ died once for all, why is the Mass a sacrifice?
- Why baptize babies who cannot yet believe?
- Can a Catholic know they are saved?
