Yes, the Word of God says the "church" is either the whole set of all believers in Jesus Christ or a local group of them. It's people who together make up His "body" while He is the "head." Example verses:
False teaching that contradicts God's Word often tries to elevate specific people or buildings while the Word elevates Christ. Over time, more religions started focusing a lot on their buildings. They identified as Christian even though their practices were getting further and further from Biblical examples. This caused much confusion.
Our church would just call it an old building that used to house a church (group of people). Hopefully, the members are still gathering to worship God, read the Word, share Christ, and love each other. Those are what's important.
I was only talking about Christians that put God's Word center. Catholicism is a different, church-centered faith that came later.
For example, in Christianity, they only venerate God and pray to God through Jesus alone. Peter and Hebrews says we are all priests who have direct access to God, coming boldly, as His adopted sons and daughters. Jesus also represents us before God with nobody else really needed.
Whereas, Catholicism taught people to venerate and pray to mere humans. They pray to Mary hoping she will represent them, too. That's idolatry in God's Word. It's also something we don't see Apostles or believers doing.
I noted below numerous such reasons that Catholicism is a different religion which Jesus and the Apostles call false teaching. That is, anything that contradicts their Gospel of justification by faith in Christ alone worshiping God alone.
Deuteronomy requires testing any person or claim that allegedly comes from God. They had to have supernatural power and never contradict God's Word. The Pope's fail that test while Apostles passed it. To be obedient, I tested it myself above.
