Ecumenism has obscured the truth of the bible and the church. Ecumenism is against the uniqueness of Jesus Christ and his gospel. Ecumenicals are against the Christian mission and evangelism. Visible organizational unity of the church and also the unity of all other religions are their major objectives. Hence the unification of the religious groups is falsely considered as the mission of the Church. The contemporary false ecumenism is the embodiment of the degeneration of the concept of unity in spirit to organizational unity. It is the solution of man, not of God. It is the master stroke of devil which plunged the Church deep into unbelief. Emphasis is shifted from the Biblical mission of evangelism to efforts toward mobilizing a visible Church organization. All energy is spent on the organizational affairs of the Church. Evangelism was replaced by Church management. The modern ecumenical liberal theology is influenced by the philosophies of the world. Here preference is given to the views of men not of god. Ecumenism takes the unfortunate and cowardly stand that since other views do not accept us, we must change and adopt some of their beliefs, conglomerate or syncretize, so that we can move toward a peaceful coexistence. This means the ecumenical want the Christians to surrender our convictions to those who have a different set of beliefs. Their marathon dialogues with other faiths ultimately end up in compromising or even denying the uniqueness of Christ and declaring moratorium on the proclamation of gospel. Modern ecumenical theology is pluralistic, relativistic, subjectivistic, inclusivistic and universalistic for destroying the objective and exclusive claims of Jesus Christ. New age is in the Church under the garb of modern liberal theology. Liberal theology facilitates the infiltration of the new age movement and pantheistic mysticism into the church through environmentalism. Environmental protection including love and concern for animals are major issues on the agenda of the ecumenicals. Modern liberal theology is the product of the new age philosophy. It has deviously misdirected the mission of the church into social work, environmental protection, and ecumenism. There is relationship between contemporary ecumenical movement, one world religion, antichrist and the ideology of liberal theology. Ecumenism is the program for the unity of world religions for the rule of false prophet and antichrist. Ecumenicals are the agents of antichrist for forming the world religion by fusing Christianity with other religions. The world religious system will try its level best, through all subtle ways and means, to eliminate the pure gospel from the face of the earth. True unity cannot be accomplished by pretending that there are no differences, but only by recognizing and respecting those differences, while focusing on the great truths of Christian faith. Here in this book, one of the biggest attacks on the Christian truth is exposed.
