You do not have to be Catholic to come. You will not be asked where you stand, and nobody will try to close a sale. The posture is the one Philip used with Nathanael: come and see.

Rome is the natural place to start because it answers questions by showing rather than telling. Why do Catholics have a Pope? Here is the fisherman's grave he sits above. Why relics, why saints, why the extraordinary churches? Walk into the catacombs, stand in St. Peter's, watch what happens at Mass. Assisi adds a man whom almost everyone, of any faith or none, already admires, and a town small enough to take in on foot.

Our Catholic Curious departures are the same itineraries with the same daily Mass; the difference is that the priest and host are chosen for their ease with honest questions, and evening conversations are built for them. Mass is open to all; only Communion is reserved to Catholics, and a guest simply stays seated or comes forward for a blessing. Catholics travel on these departures too, usually with the person who is curious.
