The Holy Apostle Thaddaeus
The Gospel According to Mark 3:13-21
At that time, Jesus went up on the mountain, and called to him those whom he desired; and they came to him. And he appointed twelve, to be with him, and to be sent out to preach and have authority to cast out demons: Simon whom he surnamed Peter; James the son of Zebedee and John the brother of James, whom he surnamed Boanerges, that is, sons of thunder; Andrew and Philip and Bartholomew, and Matthew, and Thomas, and James the son of Alphaios, and Thaddaios, and Simon the Cananaean, and Judas Iscariot, who betrayed him. Then he went home; and the crowd came together again, so that they could not even eat. And when his family heard it, they went out to seize him, for people were saying, "He is beside himself."
