I do not know Richard or Lindsay Roberts. Nor do I know the faculty members and how credible they are. I've met Richard Roberts once, and have corresponded with him two or three times. In those few correspondences, Brother Richard has always given me a gracious and courteous response. People whom I trust who know well Richard and Lindsay have vouched to me for their integrity.
When you are in ministry, you get used to people making up stories and telling lies about you. It just goes with the territory. So the allegations might be totally true, totally false, or a mixture of truth and lies. I don't know. I lean towards thinking that when all the dust settles, little of the allegations will have been proven true.
I urge everyone to refrain from pre-judging this situation. Wait until all the facts are in, and see what is proven or disproven in a court of law. Until then, assume the best of our brother and sister in the Lord and please pray for them and their families.
