Scripture calls believers... ‘the Body of Christ’....not a building or denomination.
“To the Church of God in Corinth...to those sanctified in Christ Jesus and called to be Holy, ‘together’ with ALL those ‘everywhere’ who call on the name of the Lord Jesus Christ-their Lord and ours.” I Cor. 1:2
And this was to the Corinthian church in spite of the fact there were many errors Paul had to correct....he still recognized them as believers “sanctified” ...not because of any conduct of their own but because of their relationship to Christ. (Positionally sanctified).
The Church was founded by Christ through Peter, whom He made the Church's earthly father (see Matthew 16:18-19)
The Church is one and unified, not comprised of 33,000 competing denominations. (see Matthew 12:25, 16:18, John 10:16, John 17:20-23, Acts 4:32, Romans 12:5, Romans 16:17, 1 Corinthians 1:10-13, Corinthians 3:3-4, Corinthians 10:17, Corinthians 11:18-19, Corinthians 12:12-27, Corinthians 14:33, 2 Corinthians 12:20, Ephesians 4:3-6, Philippians 1:27, 2:2-3, 1 Timothy 6:3-5, Titus 3:9-10, James 3:16, 2 Peter 2:1),
The Church is universal(ie, "katholikos" in Greek, or "Catholic") (see Matthew 28:19–20, Revelation 5:9–10)
The Church is Apostolic (see Matthew 16:18-19, Matthew 9:6-8, John 20:21-23, Acts 5:5, Ephesians 2:19–20)
The Church s hierarchical and has bishops (episkopos), priests (presbyteros or "elders"), and deacons (diakonos) (see Acts 1:20, Acts 15:2-6, Acts 20:28, Acts 21:18, Philippians 1:1, 1 Timothy 3:1-2, 1 Timothy 5:17, Titus 1:7, Hebrews 11:2, 1 Peter 5:1, 1 Peter 2:25)
The Church is continuous, existing in a single unbroken Apostolic succession of the bishops (episkopos) to bishops through the laying on of the hands, to the original Apostles. (see 1 Timothy 4:12)
