The priest here is trying to force the congregation to sing at high masses. He says that Pius X had his whole congregation singing, and I frankly asked the question, "Did Pius X say that women should not sing in church?" And he answered my question by asking, and then answering the question in the video, "Why did Pius X say that women shouldn't sing in church?"
The entire reason I asked the question, was to illustrate that the priest at my Church now, is a liar, saying that Pius X wanted congregational singing, which totally contradicts what Pius X said in his own writing in 1903. That singing in Church is a "real liturgical office," and "therefore women are excluded" from singing.
If you don't have women singing in a choir, certainly you're not going to have them commingled in the congregation singing right alongside the men.
