August 24
Saint Bartholomew is invoked as patron of leatherworkers. Saint Bartholomew is named in all four Synoptic apostolic lists (Matthew 10:3, Mark 3:18, Luke 6:14, Acts 1:13) but never appears with this name in the Gospel of John. The Synoptic lists pair him consistently with Saint Philip; in John, Philip is paired with Nathanael of Cana of Galilee (John 1:45-51, 21:2).
