Dear brothers and sisters in Christ, today we celebrate the Feast of Saint Thomas, the Apostle who is often remembered for his doubts and his quest for proof. But as we reflect on his story, let us also see the beautiful lesson he teaches us about faith and what Saint Paul called, “citizenship in God's household.” In the first reading from Ephesians, we hear that we are no longer aliens or foreign visitors, but citizens like all the saints. We are part of a building that has the apostles and prophets as its foundation, and Christ Jesus as its cornerstone. As we grow in faith, we are being built into a house where God lives in the Spirit.
