For some time now Catholic evangelists Keith and Iwona Major have worked with The Send founder Lou Engle and IHOPKC’s Mike Bickle to unify Catholics and Protestants.
Lou Engle states, “Keith and Iwona Major are a bridge to helping the Evangelical and Catholic worlds become one. I bless this couple for all they are doing.”  (emphasis added)
This is reason enough to avoid The Send conference (February 2019), and any other spiritual endeavor cobbled together by Engle. Many of those scheduled to speak or perform at The Send also seem oblivious to the difference between Catholic and Christian theology.
For the third time Catholics will participate in in the International House of Prayer’s Onething conference, scheduled Dec. 28-31, 2018. 
In 2015, speaking with Keith Major, leader of that year’s Onething Catholic Ecumenical Track, IHOPKC founder Mike Bickle stated:
Well we have so much to learn from all over the Body of Christ–Catholics, charismatics, non-charismatics, denominations, anyone who loves Jesus. That’s why we’re hosting an ecumenical track, or actually you’re the one leading it, and I so appreciate you doing that, because if you love Jesus and the Word of God, man, we’re going on the same direction before the Lord, and we love that. Thank you. (see video)
But Catholics and Protestants are not going in the “same direction before the Lord.” According to the Vatican document Lumen Gentium, a Muslim who is true to his Islamic faith will be saved! A Catholic friend of mine tried to explain that this teaching is, well, nuanced. But it is not. It is right there in black and white.
According to Lumen Gentium:
But the plan of salvation also includes those who acknowledge the Creator. In the first place amongst these there are the Muslims, who, professing to hold the faith of Abraham, along with us adore the one and merciful God, who on the last day will judge mankind. 
Roman Catholicism promotes a “gospel” of inclusivism.
The Bible states:
Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. (John 14:6)
Roman Catholic Bishop Robert Barron recently assured conservative talk host Ben Shapiro, a practicing Orthodox Jew, that those “outside the explicit Christian faith can be saved…” Lumen Gentium strikes again. (read article)
What is going to happen as prominent leaders like Lou Engle, Todd White, Mike Bickle and others continue to press for this Catholic/Protestant spiritual syncretism? How many of their young followers are going to be swept up in heresy?
In addition to Lumen Gentium, there will also be exposure to Catholic practices and beliefs–purgatory, praying to Mary and the saints, the Eucharist, Mary as sinless virgin, and so much more. King Solomon, blessed with wisdom, nevertheless began to worship false gods after being exposed to his pagan wives’ unholy beliefs. (1 Kings 11:1-11) The Word of God warns against Catholic/Protestant spiritual “unity,” because there is no such thing.
While there are Catholics who are saved, it is despite Catholic teaching, not because of it. Discussion of the Catholic faith is always difficult. Feelings get hurt, or people get angry, and it is all too easy to be timid when dealing with this, as Catholics are our friends, neighbors, co-workers, family members. The most loving thing we can do is speak the Truth. (see video)
The immediate problem is not the Catholics; it is false teachers like Lou Engle and Mike Bickle who continue to push for this false unity.
Despite the clear warning in the Word of God (2 Cor 6:14-17), it is likely many in the visible church will begin to accept and incorporate these unbiblical teachings. Remember, many in the church already accept certain new age beliefs, so this is not much of stretch.
Beware The Send, and beware IHOPKC. Pray for the believers who are being deceived by these leaders. A false religion is rising, and the foundation has been set.
