Is the One True Church Visible?

Are apostolic succession, baptist succession, sabbatarianism, or restorationism reasons to declare any denomination the one true church? That’s in the Bible - not! The church is built upon the foundation of all the apostles (Ephesians 2:20). One of those apostles was Thomas who started churches in south western India. Those churches were separated for 1500 years and some remain independent to this day. Are they not part of the one true church? Thomas and Bartholomew also planted the Assyrian Church much of which remains independent. The church is not visibly one but invisibly one in Christ (Galatians 3:28; 1 Peter 3:8; Philippians 2:2; 2 Corinthians 13:11; Colossians 3:14; 1 Corinthians 1:10; Acts 4:32).
