(I censored the un-Christian word above, to use a line from Ned Flanders).
The Iglesia ni Cristo are a local pseudo-Christian group that denies the divinity of Christ, the Holy Trinity, and pretty much standard Christian doctrine. They claim they are the one, true, church, and that their founder, the late Felix Ysagun Manalo, was the last true prophet of God ('sugo ng Diyos'), sent to re-establish the true church on earth after virtually disappearing in the supposed 'Great Apostasy' that occurred in the early years of Christianity. They have been accused of extremely fraudulent exegesis by many scholars and even brainwashing tactics (one of the features of their services is that you are given an 'attendance card' which you have to get signed on on Sundays and their other holy days; failure to do this warrants a visit to your home by their leaders). They are one of the fastest growing religious cults here in the Philippines, incidentally.
