That is not correct. We go by our church traditions that were developed by our church fathers after careful Bible study and through the inspiration of the Holy Spirit. They looked into the Scriptures to see what they said was commanded, what was alluded to, and what was just manmade. Those things that were not commanded were open to challenge and should give way to what is necessary. Even the founder of my childhood denomination didn't get everything right and we see a lot of things he founded thrown aside.And again, for those leaving the Catholic Church, what do they care? They have decided they can change whatever they want instead of following/adhering to the traditions handed down by the Apostles. It was decided during the Protestant Reformation people can make up their own rules.
Catholics decided to remain with the practices decided by the Apostles.
You are not arguing with the Church. You are arguing that you have just as much right as any Apostle to choose how things will be done. That's not the Church's fight, that's your fight.
