This is true. At some point it was forbidden to women to sing intra ambitum ecclesiae. I found it mentioned in a document within the website of the Pontifical Council for the Laity (link).
it is out of tolerance that we have passed today from the absolute prohibition to women to sing intra ambitum ecclesiae to the actual economy
It was also forbidden to women to read in Church, serve at the altar, et cetera. Some of those things are under the explicit direction of Sacred Scripture under the New Testament.
There is often a lot of modern feminist nonsense regarding the ways the Church should have behaved according to today’s standards. They may raise someone’s popularity but they are not worth much, ultimately. Man and woman do have equal dignity in the eyes of our Creator, but man has a role and woman another role. This is why the Lord was born a male when He took flesh. He did not discriminate or lessen the dignity of women in doing so. Au contraire, He exalted the dignity of womanhood in His Blessed Mother.
The point is that it is irrelevant to argue the ecclesiastic discipline of the past days. The Church has a discipline, and the discipline must be followed. The modern feminist-minded faithful will not be satisfied until they see the ordination of a Catholic woman to the priesthood :shrug: Which, if I am not wrong, is scheduled to take place about an hour and a half after the End of Time.
