Well, here's a few:
"This is my body" means "This is a cookie"
Water baptism is not necessary
Calvin's T.U.L.I.P
Those who say the Church Christ established is invisible
Those who believe Christ said his Church would be built on a book.
Those who believe in 'Faith Alone', even though in Scripture the only place where 'faith alone' appears is 'not by faith alone'
There are thousands more. But start with these.
And He answered and said, 'It is not good to take the children's bread and throw it to the dogs.'
Which means Christ called the Samaritan woman a bitch.
Nobody calls communion a *cookie* except Catholics who want to disparage non-Catholics.
Water baptism is not necessary and it’s not a tradition. There’s Scriptural support for that position.
Calvin’s *TULIP* is based on Scripture, not claimed extra Biblical revelation.
The church is visible and invisible. It exists visibly by the individuals who are the body of Christ, and it is not visible because it’s a spiritual building, not located anywhere in space or time.
Christ is building His church on the Rock, Himself, just as he said.
Faith alone is found in Ephesians 2:8-9 because we are saved by grace through faith in Christ and not of works. That is faith alone.
None of those things you listed can’t be found in the Bible.
