If, after knowing the facts presented in this Article, your friends remain loyal to the WCC, then their animosity is their problem, not yours. They are without excuse, for the Bible tells us to quit our sin as soon as we are aware it is sin. There are many worthy, genuine, Christian causes and organisations you and your church can give its cash to. No doubt many local churches and individuals thought that their money to the WCC was being used to promote the gospel. Marxism is not liberation to freedom, but liberation from freedom to oppression, repression and violence.
Christians can have no part in the process.
The message is very simple - remove the WCC this very day. Tell others about its murderous aims and work. Inform them about its worldly theology and Marxist leaders. Refuse to give donations. Help to lead your church back to truth and away from error.
