The World teaches:
Religions should never be discriminatory and argumentative, but united. After all, they are simply different paths up the same mountain. All churches are equivalent and should unite together, never rejecting fellowship with another, because what matters most isn’t whether or not you’ve got it right, but that you’re sincere and seeking.
But Christ teaches:
There is only one true way to heaven, and therefore, there is only one true Christian church composed of believers who are scattered throughout the world (1Cor. 3:16, Eph. 1:23, 4:12). Since we cannot see the hearts of people and know that they have faith, this is an invisible body (2 Tim. 2:19). As such, it cannot be identified with any one church body. Yet, since wherever the gospel is preached and the sacraments are administered the holy Christian church is present, and since we know Christ wants believers to come together, we call these visible gatherings churches as well. Membership in these visible churches is a commitment to the church body’s doctrine and practice, and wherever doctrine and practice are in agreement, fellowship should also exist (John 8:31, 1 Thes. 5:21,22). But Christ commands believers not to practice church fellowship with people who persist in teaching or practicing beliefs that are contrary to God’s Word (2 John 10,11). Further, God has established this public ministry of the Word. Even though all Christians have complete and equal access to God (1Pet. 2:9), God calls people to be public shepherds and servants of His church and children - servants called specifically for the task of preaching and guarding the truth about Christ (Eph. 4:11). Although Christ has provided much freedom in the organization of our churches and church offices, He has provided some principles, such as church leadership to men and not women (1 Tim. 2:11,12).
