It sounds like you feel personally hurt by the changes to the Mass, and I’m going to do my best to explain things to you in my own words. If you go through each of the stories about the changes on this website, you’ll have a greater understanding of the language used, including the word “consubstantial.”

Let’s start with the “time of turmoil in the Catholic Church.” This is something that’s been ongoing for ten years at the very least, and it is something that is constantly brought up so much by folks and comedians and in movies. So much so, that it feels like it’ll never end. In fact, the Church has gone a long way toward dealing with the situation. Quite frankly, for some, nothing the Church does will ever be enough, unless we can turn back time. This has nothing to do with the Mass changes. At all. It’s a mere distraction from what you’re actually upset about. Do you also think Penn State should close all of their sports programs and cancel all of their classes until this “time of turmoil” at the university is over?

The change from “We” to “I” for the Nicene Creed is explained very well in the article here. It’s supposed to be a personal faith. We still say it together.

The words have changed to reflect what they should have been all along. It is a more accurate translation of the Latin texts. As one thing you mentioned over and over about being a community, we are part of a world-wide community. Other languages had better translations than we did, and now ours is closer to theirs. It is now more correct.

As for the “antiquated aspects” of the RCC: Women cannot, and will never, be able to be priests. This is something that we cannot change. It’s not up to us. Jesus made the rules, and seeing as He is God, we listen. Mary said yes to God, and she wasn’t made a priest of any kind. Girl acolytes is something I cannot speak to, as I’ve never researched that. Priests cannot marry, and if you ask any of them, they’ll likely tell you that they wouldn’t if given the choice. Anullments are an unfortunate necessity.

Whether you like it or not, it truly is a step forward for the Church and is many years in the making. They are a step in the right direction. I don’t know what you are trying to achieve by commenting like this, but clearly your priest has failed at properly explaining the changes to you. I hope that you find the answers you’re looking for, but this is not something that is going to be reverted, no matter how much one might complain.
