I've heard it said that real magic will only ever be true and work if you actually believe in it
Perhaps Mooby is too reasonable to really believe. For example, here's some Catholic Altar magic for True Catholics TM
complete with powerful relics and other lala woowoo special water and oils and stuff. I especially love the reasons for "loss of consecration" ... when the special magic just flies away and the altar stops working:
II. CONSECRATION OF A FIXED ALTARhttp://en.wikisource.org/wiki/Catholic_Encyclopedia_(1913)/Consecration
At the consecration of a church at least one fixed altar must be consecrated. Altars, permanent structures of stone, may be consecrated at other times, but only in churches that have been consecrated or at least solemnly blessed. We have instances in which a simply priest has performed this rite. Walafridus Strabo, in the Life of St. Gall (ch. vi), says that St. Columban, at that time being a priest, having dedicated the church of St. Aurelia at Bregenz on the Lake of Constance, anointed the altar, deposited the relics of St. Aurelia under it, and celebrated Mass on it. But according to the present discipline of the Church, the ordinary minister of its consecration is the diocesan bishop. Without the permission of the ordinary, a bishop of another diocese cannot licitly consecrate an altar, although without such permission the consecration would be valid. One and the same bishop must perform the rite from the beginning to the end. An altar may be consecrated on any day of the year, but a Sunday or feast day is to be preferred (Pontificale Romanum). It is difficult to determine when the rite used at present was introduced. To the essentials of consecration reference is made as early as the sixth century by the Council of Agde (506): "Altars are to be consecrated not only by the chrism, but with the sacerdotal blessing"; and by St. Caesarius of Arles (d. about 542) in a sermon delivered at the consecration of an altar: "We have today consecrated an altar, the stone of which was blessed or anointed" (Migne, P.L., LXVII, Serm. ccxxx).
The ceremonies of the exposition of the relics on the evening before the day of consecration, the keeping of the vigil, the blessing of the Gregorian water, the sprinkling of the altar, and the translation of the relics to the church are the same as those described at the consecration of a church (see IV, below). When the relics have been carried to the church, the consecrator anoints with holy chrism, at the four corners, the sepulchre of the altar (see ALTAR), in which the relics are to be enclosed, thereby sanctifying the cavity in which the venerated remains of the martyrs are to rest, and then reverently places therein the case containing the relics and incenses them. Having anointed with holy chrism the nether side of the small slab that is to cover the sepulchre, he spreads blessed cement over the ledge of the sepulchre on the inside and fits the slab into the cavity, after which he anoints the upper side of the slab and the altar-table near it. He then incenses the altar, first, on every side -- right, left, front and on top -- whilst the chanters sing the antiphon "Stetit angelus"; secondly, in the form of a cross on the top, in the middle, and at the four corners, thirdly, whilst going round the altar three times. After the third incensation, the censer is given to a priest, vested in surplice, who, till the end of the consecration, continues going around the altar, incensing it on all sides, save when the bishop uses the censer. The incense symbolizes the sweet odour of prayer which is to ascend from the altar to heaven, whilst the fullness of the grace of the Holy Ghost, which is to descend on the altar and the faithful, is indicated by the prayers recited after the three unctions which follow. The consecrator then anoints the table of the altar at the middle of the four corners, twice with the oil of catechumens, and the third time with holy chrism. After each unction he goes round the altar once, incensing it continuously, the first and second time passing by the Epistle side, and third time by the Gospel side. Finally, as if to indicate the complete sanctification of the altar, he pours and spreads over its table the oil of catechumens and holy chrism together, rubbing the holy oils over it with his right hand, whilst the chanters sing the appropriate antiphon, "Behold the smell of my son is as the smell of a plentiful field", etc. (Gen., xxvii, 27, 28). When the church is consecrated at the same time, the twelve crosses on the inner walls are now anointed with holy chrism and incensed. The consecrator then blesses the incense and sprinkles it with holy water. Then he forms it into five crosses, each consisting of five grains, on the table of the altar, in the middle and at the four corners. Over each cross of incense he places a cross made of thin wax taper. The ends of each cross are lighted and with them the incense is burned an consumed. This ceremony symbolizes the true sacrifice which is thereafter to be offered on the altar; and it indicates that our prayers must be fervent and animated by true and lively faith if they are to be acceptable to God and efficacious against our spiritual enemies. Finally, the bishop traces with holy chrism a cross on the front of the altar and on the juncture of the table and the base on which it rests at the four corners, as if to join them together, to indicate that this altar is to be in future a firmly fixed and constant source of grace to all who with faith approach it. Then follow the blessings of the altar-cloths, vases, and ornaments of the altar, the celebration of Mass, and the publication of the Indulgences, as at the end of the consecration of a church.
Loss of Consecration
An altar loses its consecration: (1) when the table of the altar is broken into two or more large pieces; (2) when at the corner of the table that portion which the consecrator anointed with holy oil is broken off; (3) when several large stones of the support of the table are removed; (4) when one of the columns which support the table at the corners is removed; (5) if for any reason whatever the table is removed from the support, or only raised from it -- e.g., to renew the cement; (6) by the removal of the relics, or by the fracture or removal, by chance or design, of the small cover, or slab, placed over the cavity containing the relics. (See also HISTORY OF THE CHRISTIAN ALTAR.).
So if an electrician fixing the chandelier above the altar drops his screw driver and knocks off a special "anointed" corner the altar is fucked.
