It appears that some people do not have a clear understanding of what postmodernists and relativists mean by "coexistence." Christians rightly acknowledge the existence of other religions or faiths among the billions of people in the world. True Christians also interact with, and preach the Gospel of Jesus Christ to, people of other religions in hopes of winning such people to Jesus Christ for genuine salvation. Even Jesus and His apostles acknowledged the existence of other religions in the world (especially among the Gentiles), and they regularly preached the Gospel to people of other religions. Yet Jesus and His apostles did not regard those other religions as valid paths to salvation, but as false worship instead. In Revelation chapters 2 and 3, Jesus warned the seven churches against mixing His truth and pure worship with the falsehood and idolatry of unbelievers. He hated the doctrines of the Nicolaitans and the idolotrous, immoral practices of Jezebel. Jesus also warned against lukewarmness. I don't think Jesus would endorse religious pluralism, nor would He endorse syncretism. The coexistence of faiths is an ideology that originated with Satan and his demonic forces, it did not originate with God. Satan is the god and prince of this world (John 14:30; Ephesians 2:2; 2 Corinthians 4:4); therefore the world's religious and secular system is under his control (1 John 5:19; Revelation 12:9). Because of this, both religious pluralism and syncretism are becoming much more common in today's world, and they will culminate in the formation of the one world religious/political system of the Beast or Antichrist.
In the deepest sense of postmodernism, the term "coexist" means that ALL faiths, religions, and theologies should be tolerated and mutually respected as VALID pathways to God and salvation, that there is no such thing as a belief system that does not bring salvation. The postmodern idea of "coexistence" also implies that other sacred books besides the Bible are the inspired and authoritative Word of God, including the Koran of Islam, the Tripitaka of Buddhism, the Bhagavad Gita of Hinduism, the Analects of Confucianism, etc. In addition, postmodernist and relativists often justify deconstruction of the Bible text so that anyone can establish whatever beliefs they wish from the Bible, without conforming to fundamental, systematic Christian doctrine. Contrary to all of this, Jesus said He is the ONE and ONLY WAY to salvation, and the Church He personally established, along with the Bible's teachings, is the narrow road to life, as opposed to the broad road to destruction with other faiths/religions. This means that anyone saved by Jesus Christ will be part of the Christian Church, the Body and Bride of Christ, and they will hold to the Bible as the only source of God's inspired and authoritative Word. No one can justifiably be a convert to Christianity and another faith simultaneously (example: Chrislam, Christian Hinduism, Christian Buddhism, or Christian Wicca), because such a practice would be "touching the unclean thing," which is a violation of 1 Corinthians 10:20-22, 2 Corinthians 6:14-7:1, 2 John 1:9-11 and Revelation 18:4.
For about five years, I was once a devout supporter of postmodernism and the Emergent Church (Doug Paggit/Andy Stanley/Rob Bell/Steve Chalke/Brian McClaren), as I embraced inclusivism and relativism, until the Lord opened my eyes to the gross and disorganized nature of it all. Today, as a Bible-believing Christian, I believe in debating with non-Christians but I remain firm in what God's Word says is absolute truth. God commands Christians to love all people and to be peaceable with all people, but He does not command us to love and be peaceable at all costs; that is, to the point of apostatizing from the truth He personally revealed in the Bible. Its OK to preach the gospel of Jesus Christ to non-Christians but do not validate their religion, and don't count them as true brothers/sisters in Christ. We can speak the truth to unbelievers in love, without tolerating or compromising in a pluralistic or syncretistic manner.
