Among facts and figures cited by John Hobbins recently:
91% of all Christian outreach/evangelism does not target non-Christians but targets other Christians [IBMR Jan 2008, 29].
A sobering statistic. Most of this is probably due to Protestants not believing that Roman Catholics who believe in the holy gospel (though perhaps with only faith the size of a mustard seed) but who don’t have a conversion experience that they remember are actually Christians.
Good grief, people! Yes, the Romanist church is part of the holy catholic Church. Converting Romanists to Protestantism may be discipleship, for people to live out their baptisms in faithfulness to the call they received from the Lord, but in many cases, it’s decidedly not evangelism. Now, say an unbaptized elderly couple who barely attended worship and didn’t really believe in Christ our King was brought to the faith of our spiritual fathers: this would be evangelism.
(I realize the Church of Rome isn’t really catholic in return, but that shouldn’t determine what Protestants do about it.)
Now, that said, I think there’s no problem with going to Yucatán to help a church that ministers to the Mayans who suffer racism from other Mexicans. Just don’t think ‘winning’ a faithful Roman Catholic is evangelism.
