I have a lot of great Catholic friends. This might upset some of them that I say this. But Catholicism includes false doctrine.
Did you know that they have their own version of the Ten Commandments?
Catholics, I love you. But some of y'all are doing some weird, unbiblical stuff.
It's worth noting that no one (or church) is perfect. Each denomination has quirks, and can often skew the word of God. Even my own church does things I don't wholly agree with.
But the worship of Mary and the saints is not biblical. Full stop. Just read the Bible.
Both sides of my parent's families are Catholic, and I have spent a lot of time involved with the Catholic Church, and I truly mean it when I say I love them. I do. They are typically some of the most honest, kind-hearted, pious people I have ever known.
My late pastor used to say, "I believe you can be saved and receive the Gospel message in a Catholic Church." But he believed a lot of people are confused and deceived due to adding to - or taking away from - God's word.
What is important is that you believe that Jesus is the way, the truth, and the life. And that no one comes to the Father except through him. He is the complete means of salvation, and we are woefully inept to achieve it on our own due to our sin. No amount of works can get you to heaven, and no lack of works can separate you from it once you have received it. This is what the Bible says. If anyone tells you differently, then they are going against the Word of God.
