“You shall not worship the LORD your God in that way, for every abominable thing that the LORD hates they have done for their gods, for they even burn their sons and their daughters in the fire to their gods. Everything that I command you, you shall be careful to do. You shall not add to it or take from it.” (Deuteronomy 12:31-32)
There are many errors involved in pluralism, the belief that there are many paths to God, and that all religions contain equal truth, and should be approached that way. Aside from the fact that this brand of humanism flies directly in the face of the law of non-contradiction, the fundamental error of pluralism involves the nature and sovereignty of God. Who is the final determiner of how God is to be worshipped, God or man?
The Regulative Principle of Religion
“…essential to religion is the revelation of God's will as the regulative principle according to which man, as a servant, must engage himself. It has not been left to man to determine the manner in which he would serve God, for then he would stand above God. Anyone who engages himself in this way exalts himself above God and displeases the Lord in all his activity. "But in vain they do worship Me, teaching for doctrines the commandments of men" (Mat. 15:9).
Rather, the Lord Himself establishes for and reveals to man the regulative principle, indicating what He requires man to do and in which manner He wishes this to be accomplished. "Should not a people seek unto their God?...To the law and to the testimony: if they speak not according to this Word, it is because there is no light in them" (Isa. 8:19-20); "That ye may prove what is that good, and acceptable, and perfect, will of God" (Rom. 12:2).”

Friend, it is God, not man, who determines how He will be worshipped. Pluralism is nothing more than the modern tower of Babel, whereby men attempt to build a device that they hope will ascend them to the throne of heaven. Pluralism is simply recycled humanism, placing man above his Maker, worshipping the creature more than the Creator (Romans 1:25). All religions make mutually exclusive claims (including pluralism), and therefore cannot all be true. Pluralism insults the work of Christ, who did not suffer the cross so that men may simply bypass His sacrifice to enter into the heavenly Jerusalem.
"Enter by the narrow gate. For the gate is wide and the way is easy that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard that leads to life, and those who find it are few.” (Matthew 7:13-14)
"Truly, truly, I say to you, he who does not enter the sheepfold by the door but climbs in by another way, that man is a thief and a robber.” (John 10:1)
