Yes he is. I've learned much from him. I own a copy of his Catholicism series. Not to mention his on-going battle with the atheists. It has been helpful to me personally because I'm surrounded by them.
I've also learned much from Michael Voris and Church Militant to which I'm a subscriber. Both he and Father Barron have been instrumental in expanding and strengthening my faith. It wouldn't be inaccurate to say that in a sense I'm a child born of those two fathers. Which is why this is the first time I've posted a news item on FR because I have an affinity for Father Barron. I would be remiss though if I didn't acknowledge my fellow Catholics here on FR for their assistance in educating me about the faith as well.
I know there is conflict between the Barron and Voris schools of thought which I addressed up thread. But in the main the way I look at it is that I turn to Father Barron to, "know" and to Voris to, "know what's going on."
While I will never agree with all of Fr Barron’s theology, here is a good example of applying discernment. He puts one over the fence with the bases loaded: https://www.youtube.com/watch?v=l_OfAX5LLOI
