If the church is invisible and it is bible alone, then Christ failed to keep his promises.He did not establish any institution, He never even built a building. Real believers know each other and they do not have to be in the same denomination. Once again you prove RCs do not know Jesus. They know of Him but are sadly lacking in knowing Him, if they think He would have anything to do with an evil institution that allows children to be harmed and that sin hidden,
Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
