Such thinking may be common and it may be understandable (from a natural point of view), but it is not Christian. The Fathers of the Church are clear that the Scriptural and Traditional witness to the Adoration of the Magi indicates that these wise men, through the inspiration of the Holy Spirit, as Thomas Aquinas says, knew that the Child they were adoring was no ordinary human king.
As we read in St. Thomas's Summa Theologiae III, Q. 38, A. 8, Reply to Objection 4:
As Chrysostom says (Hom. ii in Matth. [From the supposititious Opus Imperfectum): "If the Magi had come in search of an earthly King, they would have been disconcerted at finding that they had taken the trouble to come such a long way for nothing. Consequently they would have neither adored nor offered gifts. But since they sought a heavenly King, though they found in Him no signs of royal pre-eminence, yet, content with the testimony of the star alone, they adored: for they saw a man, and they acknowledged a God." Moreover, they offer gifts in keeping with Christ's greatness: "gold, as to the great King; they offer up incense as to God, because it is used in the Divine Sacrifice; and myrrh, which is used in embalming the bodies of the dead, is offered as to Him who is to die for the salvation of all" (Gregory, Hom. x in Evang.). And hereby, as Gregory says (Hom. x in Evang.), we are taught to offer gold, "which signifies wisdom, to the new-born King, by the luster of our wisdom in His sight." We offer God incense, "which signifies fervor in prayer, if our constant prayers mount up to God with an odor of sweetness"; and we offer myrrh, "which signifies mortification of the flesh, if we mortify the ill-deeds of the flesh by refraining from them."
On this Solemnity of the Epiphany (which my particular church celebrates today), let us imitate these Wise Men, the first Gentiles to believe in Christ, and offer from our hearts the gifts of golden wisdom of mind for our King, sweet frankincense of prayer to our God, and the loving myrrh of mortification to our High Priest, Who is not unable to sympathize with our weakness.
