Ecumenism & Today's Ecumenical Movement Click here for my YouTube videos on salvation.
Ideally, Ecumenism would be interdenominational Christian unity of fundamental Bible beliefs. However, todays Ecumenical Movement is an initiative of the Catholic church and has no Biblical basis. The 1994 Evangelicals and Catholics Together Accord (ECT) is to unite Christians and Catholics ecumenically and to stand together against issues such as abortion. This alliance of so called Protestants with the Catholics has been greatly assisted by the 'creation' of the Charismatic Catholics. The book All About Speaking In Tongues, by Fernand Legrand, documents how the Pentecostals prayed with Catholics until they spoke in tongues. This event brought the conclusion that the Catholics must be brothers in Christ even though they stay in the Roman Catholic Church, pray to Mary in tongues, sing the Mass in tongues etc. Several books, explaining the clear error of tongues, including the one just mentioned, are available for free download from Today's Tongues.
Roman Catholicism has never been Christian and Catholic documents clearly state that nothing has changed in recent years...see Roman Catholicism. The documentation at this link speaks for itself and it cannot be argued that Catholicism is Christian. Despite this well known fact and God's command, "Do not be yoked together with unbelievers" (2 Cor 6:14), there is constant pressure within the Christian church to unite with Catholics under a 'Jesus loves us all' banner. Nowhere in Scripture does God encourage us to unite with the unsaved, even to fight a common cause. It is hypocrisy for Christians to unite with one error in order to stand against another error, even abortion.
The Ecumenical Movement's unity is achieved through accepting, or ignoring, the beliefs of the other denominations plus an agreement that there be no 'sheep stealing.' How can a Christian stand alongside unbelievers and not present them with the Gospel? It is far from loving to treat someone as a brother in the Lord while, in your heart, you know the person is heading to hell.
God calls His people to separation and holiness, not compromise. A very good article on Charles Spurgeon and the subject of separation from error, written by Paul Mizzi, is The Downgrade Controversy.
