It's by works, of course.
Maybe.
If you do the right ones.
All the time.
And if, if, if.....
No certainty of salvation like God has given us in Christ.
The Catholic church just leaves you hanging.
“The Catholic church just leaves you hanging”.
Catholicism is the fullness of the Christian faith. You have to be a tough, dedicated person to be a devout Catholic. It’s not for sissies, never has been. It takes total, complete dedication to be a practicing Catholic that lives their faith. Not all have all the capability to totally give their life to Christ. And that is the reason Catholics fall away from the faith. It’s too hard for them. They wanted to do it their way instead of God’s way. Every lapsed Catholic I have known in my life that came back to the faith said the exact same thing I just said.
The Catechism of the Catholic Church is one of the most beautiful documents ever written. It not only tells you how to be a devout Catholic, but tells you how to live the good life and be a happy, well adjusted member of society.
