Read what Jesus says about cutting yourself off from the body of Christ. You’re wrong.

And so was Martin “flaming hot” Luther.
To his followers the church is just a country club. To Catholics we know it’s being part of the body of Christ.

There is no salvation anywhere other than Christ alone - no church, no false works, no priests, etc.
Just His accomplished work and faith.
