Congregations who follow the Revised Common Lectionary will be reading John 2 0:1 9 -3 1 this Sunday (the second Sunday of Easter). That passage includes Thomas’s encounter with the risen Christ.
Nickel Creek has recorded a song called “Doubting Thomas” on their album Why Should the Fire Die? You can listen to it and see the lyrics on the YouTube link below.
