In the first century, after the Lord’s church was established, there were no denominations like we have today.

While the early church generally enjoyed unity by submitting to the authority of Christ alone, Paul warned of a movement that would change all of this. He wrote to the church at Thessalonica about “the apostasy” that was coming. He personified this great apostasy by calling it “the man of lawlessness” (2 Thessalonians 2:3). This “man of lawlessness” was described as one who “opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, displaying himself as being God” (2 Thessalonians 2:4). This apostasy would be characterized by certain men exalting themselves among God’s people, claiming to speak for God and exercise authority over their brethren.
