I came across this thread when I was research Dr. Richmond. While he has some good stuff, I would hesitate to call him a “rock-solid” Catholic. Here is a
link to a review of his site that cites some of the troubles.
He’s certainly got some really good stuff and directs you to the mystics, but he turns away from Church teaching as he sees fit. He justifies this by saying that the
Catechism is only a necessary minimum and he is seeking perfection.
He also gives some biblical commentary which is at times quite strange,
such as that women who do not pray with a veil will be possessed by demons. While he notes that he has received a masters in religious studies, it is unclear where he received it or what kind of theological foundations he has and thus whether accurately understands the Catholic mystical tradition.
I personally contacted him, because I didn’t understand what he meant by “eroticism,” because he didn’t seem to distinguish between the unitive purpose of marriage and a disordered desire to use and possess. He responded to me with accusation, which he has done with others as the Catholic Culture link shows.
In sum, he has good stuff but seems
proud and arrogant. He ignores or rejects Church teaching that does not conform to his personal understanding of Catholic mysticism and holy living. Often he seems to get half the truth, but he is unwilling to make necessary distinctions (or perhaps more charitably does not see the distinctions) between for example competitive sports that encourage a community of fraternity and virtue and neurotic tendencies to control others. However, there is a lot of great good on his site, but this also makes him dangerous, because it is difficult to sort out the good from the bad. At first blush, he appears to be a serious Catholic preaching the Gospel no one is willing to hear. But he gets into problems when he turns away from Church teaching.
As he notes in his “imprimatur” section, if he is a saint, then his cause will go up and his works evaluated by the Church and then we can be more sure about the worth of it. However, as for now, there are more certain sources of orthodox spirituality.
More than anything be cautious and return always to the Magisterium.
