Magi: From Wikipedia"
"Magi (Latin plural of magus, ancient Greek magos, Persian "مغ", English singular 'magian', 'mage', 'magus', 'magusian', 'magusaean') is a term, used since at least the 4th century BCE, to denote a follower of Zoroaster, or rather, a follower of what the Hellenistic world associated Zoroaster with, which was – in the main – the ability to read the stars, and manipulate the fate that the stars foretold. The meaning prior to Hellenistic period is uncertain.
Pervasive throughout the Eastern Mediterranean and Western Asia until late antiquity and beyond, Greek mágos "magian"/Magician was influenced by (and eventually displaced) Greek goēs, the older word for a practitioner of magic, to include astrology, alchemy and other forms of esoteric knowledge. This association was in turn the product of the Hellenistic fascination for (Pseudo-)Zoroaster, who was perceived by the Greeks to be the "Chaldean" "founder" of the Magi and "inventor" of both astrology and magic. Among the skeptical thinkers of the period, the term 'magian' acquired a negative connotation and was associated with tricksters and conjurers. This pejorative meaning survives in the words "magic" and "magician".
In English, the term "magi" is most commonly used in reference to the Gospel of Matthew's "wise men from the East", or "three wise men" (though that number does not actually appear in Matthew's account, and various sources placed the number anywhere between two and twelve).[citation needed] The plural "magi" entered the English language around 1200, in reference to the Biblical magi of Matthew 2:1. The singular appears considerably later, in the late 14th century, when it was borrowed from Old French in the meaning magician together with magic."
"In Christian tradition
Christian tradition states that magians visited the infant Jesus shortly after his birth. This tradition originates from the Gospel of Matthew (2:1-2:12). The twelve verses describe how certain magians from the east were notified of the birth of a king in Judea by the appearance of a star. Upon their arrival in Jerusalem, they visited King Herod to determine the location of where the king of the Jews had been born. Herod, disturbed, told them that he had not heard of the child, but informed them of a prophecy that the baby Jesus would be born in Bethlehem. He then asked the magians to inform him when they find the infant so that Herod may also worship him. Guided by the Star of Bethlehem, the wise men found the baby Jesus in a house in Bethlehem, worshiped him, and presented him with "gifts of gold and of frankincense and of myrrh." (2.11) In a dream they are warned not to return to Herod, and therefore return to their homes by taking another route. Since its composition in the late 1st century, numerous apocryphal stories have embellished the gospel's account.
The gospel's mágoi (Greek) or magūšāyā (Aramaic) is typically translated as "wizard", a meaning that is also found in the commentaries of St. Justin, Origen, St. Augustine and St. Jerome. The term appears in both Old- and New Testament with the meaning of "Magicians" (Acts of the Apostles 8:9; 13:6, 8, and the Septuagint of Daniel 1:20; 2:2, 2:10, 2:27; 4:4; 5:7, 5:11, 5:15). This is, however, "not the common interpretation".[8]
In Esoteric Christianity, one who is skilled, profound, or a master of the esoteric or a magical art is titled a 'magus' or 'mage' (as opposed to an adept, who is skilled but not a master).[9] The title is rare and is really only used in a historical context.
Hermetic Order of the Golden Dawn
The Hermetic Order of the Golden Dawn used the title of "Magus" to refer to the second-highest level of attainment in their degree system. This system, with associated titles, would later be adopted by Aleister Crowley for his occult order A∴A∴, wherein the title "Magus" designated the highest attainable grade of magic (Moses, Buddha, and Lao Tzu being some examples of those who attained this grade). To be a Magi means to journey to give gifts."
