Some about Zacharias here. I think it is the second link where there is an excerpt from an interview in 2012 where he says he regrets saying Henri Nouwen was a great saint.
"In closing this, we’ll leave this aside; and in the interest of fairness, which I’m rarely given credit for, Interview with Dr. Ravi Zacharias on his latest book, “Why Jesus?” has been brought to my attention today.
Zacharias was asked in this January 2012 interview:
If in your book, you wrote how Eastern mysticism is completely erroneous, why did you state in one of your speaking engagements that Henri Nouwen was one of the greatest saints who lived in our time, when Nouwen is known to have been influenced by Thomas Merton and others who practice Eastern mysticism? (source)
Here is his answer:
I regret having said that. At the time, I based my comment on Nouwen’s story of the prodigal son which I felt was on target. But later as I learned more about Nouwen and Merton, I found their writings to be very troubling. I believe that doctrinally, Nouwen lost his way.
I used to read Malcolm Muggeridge too until I read his book, “Jesus Rediscovered”. Muggeridge was morally and culturally a good thinker, but he was not theologically sound. (source)"
An encouraging comment from Ravi.
