Today we honor Tadeáš. Happy name day, Tadeáš!
The name Tadeáš is the Czech & Slovak form of Thaddeus, which is of Aramaic origin and means "heart". In the new Gospel of Matthew, Thaddeus is listed as one of the twelve apostles, though elsewhere in the New Testament his name is omitted and Jude's appears instead. It is likely that the two names refer to the same person.
