If Islam conquers Vatican, whom would the Iglesia Ni Cristo® side-- Muslims or Catholics?

Muslim extremists, to the rejoice of Muslim moderates who wanted to dominate within our democratic cities are waging war against the Christian Church which for them is represented by the CHURCH OF ROME, in the VATICAN CITY. [Read the News HERE and the Muslim Terrorist's MANIFESTO]

If the true church was restored in Rome and Jerusalem, why is it that the Iglesia Ni Cristo® Central is still in the Philippines?

Restoration (ROME)

But the true Church of Christ is back in the region. Three momentous occasions that happened in the mid-1990s in the cities of Rome, Jerusalem, and Athens highlight this return. They involved the registration of the Church's congregations in Italy, Israel, and Greece with these countries' respective governments. A special worship service officiated by the Executive Minister, Brother Erano G. Manalo, marked each occasion. -The Iglesia Ni Cristo Website

Then WHY is the Iglesia Ni Cristo® CENTRAL still in the Philippines if the "true church" had been returned and restored to its origin?

DECEIVERS! That's what Felix Manalo's INC™ do. 

They DECEIVE people!
