occasional profane results. In addition to providing holiday-themed entertainment, "Santa tracking" websites raise interest in space technology and exploration, serve to educate children in geography and encourage them to take an interest in science. Criticism Opposition from some Christian denominations Santa Claus has partial Christian roots in Saint Nicholas, particularly in the high church denominations that practice the veneration of him, in addition to other saints. In light of this, the character has sometimes been the focus of controversy over the holiday and its meanings. A number of denominations of Christians have varying concerns about Santa Claus, which range from acceptance to denouncement. Some Christians, particularly Calvinists such as the Puritans, disliked the idea of Santa Claus, as well as Christmas in general, believing that the lavish celebrations were not in accordance with their faith. Other nonconformist Christians condemn the materialist focus of contemporary gift giving and see Santa Claus as the symbol of that culture. Condemnation of Christmas was prevalent among the 17th-century English Puritans and Dutch Calvinists who banned the holiday as either pagan or Roman Catholic. The American colonies established by these groups reflected this view. Tolerance for Christmas increased after the Restoration but the Puritan opposition to the holiday persisted in New England for almost two centuries. In the Dutch New Netherland colony, season celebrations focused on New Year's Day. Following the Restoration of the monarchy and with Puritans out of power in England, the ban on Christmas was satirized in works such as Josiah King's The Examination and Tryal of Old Father Christmas; Together with his Clearing by the Jury (1686). Reverend Paul Nedergaard, a clergyman in Copenhagen, Denmark, attracted controversy in 1958 when he declared Santa to be a "heathen goblin" ("en hedensk trold" in Danish) after Santa's image was used on the annual Christmas stamp ("julemærke") for a Danish children's welfare organization. Mary Baker Eddy, the founder of the Christian Science movement, wrote: "the children should not be taught that Santa Claus has aught to do with this [Christmas] pastime. A deceit or falsehood is never wise. Too much cannot be done towards guarding and guiding well the germinating and inclining thought of childhood. To mould aright the first impressions of innocence, aids in perpetuating purity and in unfolding the immortal model, man in His image and likeness."
