Just as early Christians recruited Roman pagans by associating Christmas with the Saturnalia, so too worshippers of the Asheira cult and its offshoots were recruited by the Church sanctioning “Christmas Trees”. Pagans had long worshipped trees in the forest, or brought them into their homes and decorated them, and this observance was adopted and painted with a Christian veneer by the Church.
Norse mythology recounts how the god Balder was killed using a mistletoe arrow by his rival god Hoder while fighting for the female Nanna. Druid rituals use mistletoe to poison their human sacrificial victim. The Christian custom of “kissing under the mistletoe” is a later synthesis of the sexual license of Saturnalia with the Druidic sacrificial cult.
In pre-Christian Rome, the emperors compelled their most despised citizens to bring offerings and gifts during the Saturnalia (in December) and Kalends (in January). Later, this ritual expanded to include gift-giving among the general populace. The Catholic Church gave this custom a Christian flavor by re-rooting it in the supposed gift-giving of Saint Nicholas (see below).
