This is probably because the business is owned by an ethnic Chinese, who own many businesses in the Philippines but who, unlike the Filipinos, generally aren't Catholic.
>>>>>>>Oops! I forgot. Roman Catholicism itself is idolatrous.
Roman Catholicism is the world's largest Christian denomination, and Roman Catholics have spread the Faith to all corners of the earth. The claim that Roman Catholicism is "idolatrous" is moronic.
">>>>>>In business after business in the Philippines you can see, hanging on the walls, god shelves, where BOTH Roman Catholic idols and Buddhist idols are placed together, and incense is burning there.
"This is probably because the business is owned by an ethnic Chinese, who own many businesses in the Philippines but who, unlike the Filipinos, generally aren't Catholic."
NOPE. These are members of the Roman Catholic church, and big givers to it. Regardless, why wouldn't any Roman Catholic priest in the Philippines ever speak on the error of this mixture? They never would. They don't care, as long as the proper gifts are made to the church (or personally to the priests).
