INC explains the four angels on the four corners of the earth in Revelation 7:

“Ang apat na anghel na pumipigil sa hangin ay mga pinuno ng bansa, na ito’y mga sugo rin o anghel ayon sa I Ped. 2:13-14. Ang hanging pinipigil ay digmaan, gaya ng sinasabi sa Jer. 4:11-13, 19. Ito nga ang digmaang sumiklab noong 1914. Ang apat na pinuno ng bansa na kumakatawan sa pagpigil sa digmaang sumiklab noong 1914 ay sina Lloyd George ng Gran Bretanya, sina Clemenceau ng Pransiya, si Orlando ng Italya at Wilson ng Amerika. Sila ay lalong kilala sa tawag na The Big Four” (World History, p. 494).”

Translation: “The four angels holding the winds were leaders of nations, who were also messengers, or angels, as written in I Pet. 2:13-14. The wind that they were controlling refers to war as mentioned in Jer. 4:11-13, 19. This was the war that broke out on 1914. The four leaders of nations who worked on the prevention of the war, which broke out in 1914, were Lloyd George of Great Britain, Clemenceau of France, Orlando of Italy, and Wilson of America. They were better known as the Big Four” (World History, p. 494)–(Pasugo, July 1964, p. 33).

Now get this: it would be Felix Manalo to instruct George, Clemenceau, Orlando, and Wilson, NOT TO HURT THE EARTH UNTIL THEY (Manalo and these four), HAD SEALED THE 144,000 IN THEIR FOREHEADS.  Did Felix Manalo DO THIS?  No!  Did he even write letters to these four men-angels?  No!  Did he call them on the hot-line?  No!  Did he send them a telegram?  No!  Did he send a smoke signal message?  No! Did Manalo and these four men seal 144,000 in their foreheads with the seal of God?  No!  Did Manalo and these four men even try to seek out the 144,000 from the 12 tribes of Israel?  No!  Manalo came to America we are told in 1919 and did not even send a post card to President Wilson. Lies, Lies, Lies, and these people really believe they are the true Church of Christ?  They are so deceived!  Why will these members not open their eyes?  It is because they have their religion and right or wrong, going to hell or not unsaved, they will not allow truth to come into their heart.
