In the New Testament, one of the original Twelve Apostles chosen by the Savior during his mortal ministry. In Greek the name is Didymus (Matt. 10:2–3; John 14:5; 20:24–29; 21:2). Though Thomas doubted Jesus’ resurrection until he personally saw the Savior, his strength of character made him willing to face persecution and death with his Lord (John 11:16; 20:19–25).
