from WordNet (r) 3.0 (2006)

Thaddaeus
    n 1: (New Testament) supposed brother of St. James; one of the
         Apostles who is invoked in prayer when a situation seems
         hopeless [syn: {Jude}, {Saint Jude}, {St. Jude}, {Judas},
         {Thaddaeus}]

from Easton's 1897 Bible Dictionary

Thaddaeus
breast, the name of one of the apostles (Mark 3:18), called
"Lebbaeus" in Matt. 10:3, and in Luke 6:16, "Judas the brother
of James;" while John (14:22), probably referring to the same
person, speaks of "Judas, not Iscariot." These different names
all designate the same person, viz., Jude or Judas, the author
of the epistle.
