Was it 3 wise man or 3 kings?
No Father of the Church holds the Magi to have been kings. Neither were they magicians: the good meaning of magoi, though found nowhere else in the Bible. These Magians can have been none other than members of the priestly caste. The religion of the Magi was fundamentally that of Zoroaster and forbade sorcery; their astrology and skill in interpreting dreams were occasions of their finding Christ. The Gospel narrative omits to mention the number of the Magi, and there is no certain tradition in this matter. Some Fathers speak of three Magi; they are very likely influenced by the number of gifts. In the Orient, tradition favours twelve.
