Ecumenicalism is just a word. However, in these last days it has come to mean much more than the ‘promoting or tending tending toward worldwide Christian unity or cooperation’ that we see in the dictionary definition. To the ecumenicists, it states that Christianity is the same regardless of definition of the Gospel of our Lord Jesus Christ. In fact, that is not even mentioned. Instead, they focus on calling those who attempt to emulate Christ’s humanism or good works their brothers. This has to be the case, because those who come together as “one” to stand against certain political or cultural issues actually claim to hold to doctrines that are mutually exclusive. However, as we see with the the recent actions of Rick Warren with his declaration that the Pope is the “Pope of all Christians,” for example, the ecumenicists are willing to overlook these differences as if they are negotiable.
