In many - not all - Protestant groups, going from one group to another is not analogous to a Catholic leaving the Catholic Church. It is more like a Catholic who decides to join a TLM parish or the Eastern Catholic Church. I don't think it is going to be terribly helpful to compare the two.
I'm not saying they equate in every way. My point is trusting in God, reading Scripture & fellowship. Following Christ & producing good fruit. A person does not need to be Catholic to do this.
A protestant leaving Church for a time or leaving for another does not compare to Catholics leaving for TLM or whatever. You'll hear everytime it is going where one feels spiritually fed & growing spiritually.
They do not see it as leaving Christ & somehow that particular Church hinges on their salvation. They trust Christ for their salvation.
Who saves? Christ or the Church? The Church is an
aid to our salvation & supposed to be a light to a dark world.
It seems Catholics check off lists for their salvation of do's & don't to get their salvation points in because they worry so much about the Church being the true Church. In between time they worry about screwing up & getting to confession before they die & burn in Hell. They pour over documents & theology usually to the exclusion of Christ & Scripture.
There is joy in the Catholic faith. But I wonder why some feel shackled by it to the point of being afraid to leave it if they do not believe what She teaches. Even the Church acknowledges that people can leave out of ignorance which they are not responsible for.
Or they just try to change it from the inside regardless of what the Church teaches.
Faith is hard no matter where you sit. But Faith is also supposed to be a comfort. A lot of Catholics are miserable & seem to find no comfort in the faith. Unlike protestants which we will see in heaven as well.
Protestants seem to possess a peace & freedom in their faith in Christ that Catholics sorely lack.
So where does this fear stem from? Is it of God? Does God mean for us to live our faith miserably?
I don't think so.
