Nathanael

A disciple of Christ, probably the same as BARTHOLOMEW, which see. He was a native of Cana in Galilee, John 21:2, and was one of the first to recognize the Messiah, who at their first interview manifested his perfect acquaintance with Nathanael’s secret heart and life, John 1:45-51. He was introduced by Philip to Jesus, who on seeing him pronounced that remarkable eulogy which has rendered his name almost another word for sincerity: "Behold an Israelite indeed, in whom is no guile." He was one of the disciples to whom Christ appeared at the sea of Tiberias after his resurrection, John 21:2; and after witnessing the ascension returned with the other apostles to Jerusalem, Acts 1:4,12,13.

Nathanael

Given or gift of God, one of our Lord's disciples, "of Cana in Galilee" (John 21:2). He was "an Israelite indeed, in whom was no guile" (1:47,48). His name occurs only in the Gospel of John, who in his list of the disciples never mentions Bartholomew, with whom he has consequently been identified. He was one of those to whom the Lord showed himself alive after his resurrection, at the Sea of Tiberias.

Nathanael

(gift of God ), a disciple of Jesus Christ, concerning whom, under that name at least, we learn from Scripture little more than his birthplace, Cana of Galilee, (John 21:2) and his simple, truthful character. (John 1:47) The name does not occur in the first three Gospels; but it is commonly believed that Nathanael and Bartholomew are the same person. The evidence for that belief is as follows: St, John who twice mentions Nathanael, never introduces the name of Bartholomew at all. St. Matthew, (Matthew 10:3) St. Mark, (Mark 3:18) and St. Luke, (Luke 8:14) all speak of Bartholomew but never of Nathanael. If was Philip who first brought Nathanael to Jesus, just as Andrew had brought his brother Simon.
