That doesn’t help identify the Church. You’re saying that if two or three Baptists come together in Jesus’ name, that is the Church;Mat 18:20 Whenever two or three of you come together in my name, I am there with you.
His church meets in a home, a cafe, a field, on the beach, in the office, in school, an airport, a prison, a hospital, a ship, in fact anywhere where two or three are gathered together in the name of Jesus because he has promised to be there with us.
if two or three Catholics come together in Jesus’ name, that is the Church;
if two or three Lutherans come together in Jesus’ name, that is the Church;
if two or three SDAs come together in Jesus’ name, that is the Church;
if two or three evangelicals come together in Jesus’ name, that is the Church;
if two or three Anglicans come together in Jesus’ name, that is the Church;
if two or three Presbyterians come together, that is the Church.
But that can’t be right, because 1Tim 3:15 says the Church is the “pillar and foundation of the TRUTH”, so the Church teaches only ONE truth - ie, ONE set of doctrines. Baptists, Catholics, Lutherans, SDAs, evangelicals, Anglicans and Presbyterians all teach DIFFERENT DOCTRINES, so they can’t all be the Church, because different doctrines can't possibly be the "truth". According to 1Tim 3:15, the Church teaches ONE truth, not different “truths”.
Your definition of “the Church” is nothing at all like the Church described in Acts. For example, Paul certainly did not consider that any “two or three” Christians gathered in Jesus’ name to be “the Church”. Did he go to any “two or three” Christians gathered in Jesus’ name to have his preaching approved (Gal 2:1-2) and to settle doctrinal matters (Acts 15:2-3)? No, he went to the recognized leaders of the Church in Jerusalem.
And it was not just any “two or three” Christians gathered in Jesus’ name who decided doctrinal matters, such as the matter of circumcision in Acts 15. It was the recognized leaders of the Church in Jerusalem who decided what doctrine was to be.
Furthermore, Jesus did not give “the keys of the kingdom of God” to just any “two or three” gathered in his name - Jesus gave the “keys” to one man, Peter, the first leader of the Church.
You can’t tell me where the Church described in Acts is to be found today - it must exist, because Jesus promised that his Church will never be destroyed - Matt 16:18.
