I must say, after reading the news regarding WARC and WEC, it is rather scary.
I wonder if this sort of unity has more to do with a Reformed Church or just "Unity". For it has been clear to me after visiting some of the so called reformed churches which are congregated mostly by westerners, that they have stopped learning the Bible with the wisdom passed down by great reformers, instead, they are more interested in keeping the superficial pride of tradition, some even associate this pride to their ethnicity and if not so, they would follow the World Peace concept of John Lennon which was merely a minion of the Babel Tower in disguise.
Those who follow this path of world peace do not realize that they are giving God's glory for others to step upon.
As a reformer, I find myself truly abhorred by the foolish ecumenical movement, but at the same time, regretting that I did not do enough. May my Lord bless with mercy to move me forward absolutely in His full guidance and instructions.
