The article below is the video description as posted on YouTube.
There were two videographers, since it was a special Mass. The incident was caught on tape by accident. Watching it I can say that the lady walked up, knelt down and was ready to receive Communion. Bishop Brown immediately grabs her hands (not violently, it seems) and says something - I think I can make out 'scene...up'(a Mexican oompahpah oompapah 'Communion song' drowns out everything else). The lady's own account recounts it like this:
I was sitting on the side of the Church, 3rd row, where Bishop Tod Brown distributed the Holy Eucharist, (in the video, I am the woman with short brown hair and glasses, wearing a black sweater and long white skirt sitting on the opposite side (from the camera) of the aisle in the center of the church) and upon approaching the Bishop to receive, I genuflected, out of reverence for the Sacred Species and remained on one knee to receive the Blessed Sacrament. Bishop Brown refused to give me Holy Communion. Bishop Brown said, "You need to stand up".
I was in shock and didn't move or respond. He then reached out and took hold of my folded hands, attempting to physically pull me to a standing position, and said more sternly, "You need to stand."
I looked up and whispered, quietly and respectfully, "Please, bishop", and he then grabbed my arm, and pulled me, as though to physically pull me up to a standing position (although obscured, you can see where he bends down and extends his right arm to grab mine) as he stated more loudly, "Get up".
Still on one knee, I then asked very quietly and with genuine ignorance, "Why?"
As he stood up straight he responded, very loudly and sternly, "Because THAT'S the way we receive communion. Now, GET UP, you're causing a scene.'
He gives her Communion after she gets up. From viewing the tape, I have to say that if he had given her Communion right away, there wouldn't even have been any delay, she wasn't putting on a show or anything. Even after he grabbed her twice, she bowed her head briefly, got up, received Communion and left right away.
From the Vatican (Congregation for the Divine Liturgy):
Even where the Congregation has approved of legislation denoting standing as the posture for Holy Communion, in accordance with the adaptations permitted to the Conferences of Bishops by the Institution Generalis Missalis Romani n. 160, paragraph 2, it has done so with the stipulation that communicants who choose to kneel are not to be denied Holy Communion on these grounds.
There is even an open letter published in Renew America calling the bishop's attention to this "scene" as the bishop put it and other matters such as his implicit support for gay marriage.
This is an old article but it shows how very active Catholics are in watching over their bishop. Kinda ironic, eh? The flock shepherding their shepherd.
Latest news reports are saying that this Bishop Tod hid sexually abusive priests like his close friend and classmate of this sorry excuse for a Catholic priest-bishop-and-cardinal!
