“There are people in other religions who are being led by God’s secret influence to concentrate on those parts of their religion which are in agreement with Christianity, and who thus belong to Christ without knowing it. For example, a Buddhist of good will may be led to concentrate more and more on the Buddhist teaching about mercy and to leave in the background (though he might still say he believed) the Buddhist teaching on certain other points. Many of the good Pagans long before Christ’s birth may have been in this position. And always, of course, there are a great many people who are just confused in mind and have a lot of inconsistent beliefs all jumbled up together. Consequently, it is not much use trying to make judgments about Christians and non-Christians in the mass.” — C.S. Lewis
That sounds rather unorthodox from the teaching of most churches today, but I never hear anyone criticize Lewis as a heretic, or any other cynical label.
People today would also have problems with Deitrich Bonhoeffer and Karl Barth for what they say on religionless Christianity and bibliolatry (the Bible as idolatry). If people have problems with your theology, there’s a good chance you’re in Divine company.
