Magi Kings: Good or bad?
We have all heard about the three Magi King! But in reality are they in fact kings, magicians, astrologers, astronomers or something else?
The reason some denominations may or may not liturgically celebrate their memory, will vary according to their specific way of holding church services. Some denominations are more liturgically structured than others. Less liturgically structured denominations will place less importance to holding a special day to their memory (Feast of the Epiphany).
Some may hold that the Magi were in fact pagan magicians or something similar , but most will agree that they simply the Wise from the East.
For Catholic, they were the ”Wise Men from Orient. We do not even know their true number. Here in the West there were three, but in the East the prevailing number is twelve (12) Magi.
We should not associate the word Magi with magicians, but rather with Wise Men.
The "wise men from the East" who came to adore Jesus in Bethlehem (Matthew 2).
Rationalists regard the Gospel account as fiction; Catholics insist that it is a narrative of fact, supporting their interpretation with the evidence of all manuscripts and versions, and patristic citations. All this evidence rationalists pronounce irrelevant; they class the story of the Magi with the so-called "legends of the childhood of Jesus", later apocryphal additions to the Gospels. Admitting only internal evidence, they say, this evidence does not stand the test of criticism.
John and Mark are silent. This is because they begin their Gospels with the public life of Jesus. That John knew the story of the Magi may be gathered from the fact that Irenaeus (Adv. Haer., III, ix, 2) is witness to it; for Irenaeus gives us the Johannine tradition.
Luke is silent. Naturally, as the fact is told well enough by the other synoptics. Luke tells the Annunciation, details of the Nativity, the Circumcision, and the Presentation of Christ in the Temple, facts of the childhood of Jesus which the silence of the other three Evangelists does not render legendary.
Luke contradicts Matthew and returns the Child Jesus to Nazereth immediately after the Presentation (Luke 2:39). This return to Nazareth may have been either before the Magi came to Bethlehem or after the exile in Egypt. No contradiction is involved.
*Who the magi were
Non-Biblical evidence
We may form a conjecture by non-Biblical evidence of a probable meaning to the word magoi. Herodotus (I, ci) is our authority for supposing that the Magi were the sacred caste of the Medes. They provided priests for Persia, and, regardless of dynastic vicissitudes, ever kept up their dominating religious influence. To the head of this caste, Nergal Sharezar, Jeremias gives the title Rab-Mag, "Chief Magus" (Jeremiah 39:3, 39:13, in Hebrew original — Septuagint and Vulgate translations are erroneous here). After the downfall of Assyrian and Babylonian power, the religion of the Magi held sway in Persia. Cyrus completely conquered the sacred caste; his son Cambyses severely repressed it. The Magians revolted and set up Gaumata, their chief, as King of Persia under the name of Smerdis. He was, however, murdered (521 B.C.), and Darius became king. This downfall of the Magi was celebrated by a national Persian holiday called magophonia (Her., III, lxiii, lxxiii, lxxix). Still the religious influence of this priestly caste continued throughout the rule of the Achaemenian dynasty in Persia (Ctesias, "Persica", X-XV); and is not unlikely that at the time of the birth of Christ it was still flourishing under the Parthian dominion. Strabo (XI, ix, 3) says that the Magian priests formed one of the two councils of the Parthian Empire.
Biblical evidence
The word magoi often has the meaning of "magician", in both Old and New Testaments (see Acts 8:9; 13:6, 8; also the Septuagint of Daniel 1:20; 2:2, 2:10, 2:27; 4:4; 5:7, 5:11, 5:15). St. Justin (Tryph., lxxviii), Origen (Cels., I, lx), St. Augustine (Serm. xx, De epiphania) and St. Jerome (In Isa., xix, 1) find the same meaning in the second chapter of Matthew, though this is not the common interpretation.
Patristic evidence
No Father of the Church holds the Magi to have been kings. Tertullian ("Adv. Marcion.", III, xiii) says that they were wellnigh kings (fere reges), and so agrees with what we have concluded from non-Biblical evidence. The Church, indeed, in her liturgy, applies to the Magi the words: "The kings of Tharsis and the islands shall offer presents; the kings of the Arabians and of Saba shall bring him gifts: and all the kings of the earth shall adore him" (Psalm 72:10). But this use of the text in reference to them no more proves that they were kings than it traces their journey from Tharsis, Arabia, and Saba. As sometimes happens, a liturgical accommodation of a text has in time come to be looked upon by some as an authentic interpretation thereof. Neither were they magicians: the good meaning of magoi, though found nowhere else in the Bible, is demanded by the context of the second chapter of St. Matthew. These Magians can have been none other than members of the priestly caste already referred to. 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. (See: THEOLOGICAL ASPECTS OF THE AVESTA.)
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. Early Christian art is no consistent witness:
a painting in the cemetery of Sts. Peter and Marcellinus shows two;
one in the Lateran Museum, three;
one in the cemetery of Domitilla, four;
a vase in the Kircher Museum, eight (Marucchi, "Eléments d'archéologie chrétienne", Paris, 1899, I 197).
The names of the Magi are as uncertain as is their number. Among the Latins, from the seventh century, we find slight variants of the names, Gaspar, Melchior, and Balthasar; the Martyrology mentions St. Gaspar, on the first, St. Melchior, on the sixth, and St. Balthasar, on the eleventh of January (Acta SS., I, 8, 323, 664). The Syrians have Larvandad, Hormisdas, Gushnasaph, etc.; the Armenians, Kagba, Badadilma, etc. (Cf. Acta Sanctorum, May, I, 1780). Passing over the purely legendary notion that they represented the three families which are descended from Noah, it appears they all came from "the east" (Matthew 2:1, 2, 9). East of Palestine, only ancient Media, Persia, Assyria, and Babylonia had a Magian priesthood at the time of the birth of Christ. From some such part of the Parthian Empire the Magi came. They probably crossed the Syrian Desert, lying between the Euphrates and Syria, reached either Haleb (Aleppo) or Tudmor (Palmyra), and journeyed on to Damascus and southward, by what is now the great Mecca route (darb elhaj, "the pilgrim's way"), keeping the Sea of Galilee and the Jordan to their west till they crossed the ford near Jericho. We have no tradition of the precise land meant by "the east". It is Babylon, according to St. Maximus (Homil. xviii in Epiphan.); and Theodotus of Ancyra (Homil. de Nativitate, I, x); Persia, according to Clement of Alexandria (Stromata I.15) and St. Cyril of Alexandria (In Is., xlix, 12); Aribia, according to St. Justin (Cont. Tryphon., lxxvii), Tertullian (Adv. Jud., ix), and St. Epiphanius (Expos. fidei, viii). - Magi
Thus all taken into consideration, the Magi must be good souls who saw the reality that of adoring the Child Jesus as a good thing!
Herod on the other hand, was one very bad dude and wanted the Newborn King’s death! His very plans were fouled up by these same Magi from Orient!
Again some denominations hold that after the resurrection, they were converted to Christianity by the Apostles.
Catholics for example hold them as saints and their remains are in the Cologne Cathedral in the Tomb of the Three Kings

Chapel of the Magi, Cologne Cathedral, where the Shrine of the Three Kings was kept from 1322 till 1948.
