It is against the teachings of God, and of the Holy Scripture, that other churches is built in other places, let's say in the US, or in England, or in Germany, or in Rome. They also claim that another church had also been founded in the Philippines. The truth is, God did not give any right to anybody to build his own church. It is indeed disgusting that today, a lot of ministers build churches of their own. They deliberately oppose and defy what the Bible said - that, the Gentiles, like us, must join or make ourselves a part of the body, or the Church, for us to be saved.
And what is the reason why we must abide by it? It is because, as far as God is concerned, He did not give anybody His consent to build a church right now in our time. This is what Psalms 127:1 says-
"Except the Lord build the house, they labour in vain that built it: except the Lord keep the city, the watchman waketh but in vain."
The verse mentioned of a "house," which becomes useless if it is not built by the Lord. Let us now ask the Bible. What is being referred to as the "house," which only God has the right to build? In I Timothy 3:15, it says-
"But if I tarry long , that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth."
If you have noticed, in the New Testament, the word house refers to the Church of God. This is, truly, the house of God because it was built by God, Himself. That is why, if, in our time, you come across churches, whose founders are also their ministers, you can be sure that they are NOT REAL!
