QUOTE:
Crucifixion in the Philippines is a devotional practice held every Good Friday, and are part of the local observance of Holy Week. Devotees or penitents called magdarame in Kapampangan are willingly crucified in imitation of Jesus Christ's suffering and death, while related practices are carry wooden crosses, crawling on rough pavement, and self-flagellation.
Penitents considered these acts to be mortification of the flesh, and undertake these to ask forgiveness for sins, to fulfil a panatà (Filipino, "vow"), or to express gratitude for favours granted.
These customs are strongly discouraged by the Catholic Church in the Philippines, which considers them to be fanatical, superstitious expressions of Folk Catholicism and self-harm contrary to its teachings on the body. The Department of Health meanwhile often insists that participants in the rites should have tetanus shots and that the nails used should be sterilized.[1]

That's your Wiki-message of the day. If you ask a Pinoy, they may offer a more subjective response, which reflects the personal, human side of such activities.
