From Pope Francis:
During a daily Mass last week, Pope Francis called ideological Christianity “an illness” that doesn’t serve Jesus Christ. Instead, it “frightens” people and pushes them away from religion.
“In ideologies there is not Jesus: in his tenderness, his love, his meekness. And ideologies are rigid, always. Of every sign: rigid. And when a Christian becomes a disciple of the ideology, he has lost the faith: he is no longer a disciple of Jesus, he is a disciple of this attitude of thought” For this reason Jesus said to them: ‘You have taken away the key of knowledge.’ The knowledge of Jesus is transformed into an ideological and also moralistic knowledge, because these close the door with many requirements. The faith becomes ideology and ideology frightens, ideology chases away the people, distances, distances the people and distances of the Church of the people. But it is a serious illness, this of ideological Christians. It is an illness, but it is not new, eh?”
That second paragraph reveals deadliness at the core. But I see it on both sides on a regular basis.
