Not really. it's like 80% Catholic and 20% Muslim.
edit: from the wiki article
The Philippines is one of only two majority Roman Catholic countries in Asia (the other being East Timor). About 90% of Filipinos are Christians, where 81% belong to the Roman Catholic Church, and the 9% composed of Protestant denominations, the Philippine Independent Church, and Iglesia ni Cristo. While Christianity is a major force in the culture of the Filipinos, indigenous traditions and rituals still influence religious practice.
Approximately 5% of Filipinos are Muslims, and are locally known as "Moros", having been dubbed this by the Spanish due to their sharing Islam with the Moors of North Africa. They primarily settle in parts of Mindanao, Palawan and the Sulu archipelago, but are now found in most urban areas of the country. Most lowland Muslim Filipinos practice normative Islam, although the practices of some Mindanao's hill tribe Muslims reflect a fusion with animism. There are also small populations of Buddhists, Jews and animists, which, along with other non-Christians and non-Muslims, collectively comprise 5% of the population.
