26. They were united and “added unto” (Acts 2:1, 41).
And when the day of Pentecost was fully come, they were all with one accord in one place. (Acts 2:1)
Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls. (Acts 2:41)
Even though the verses cited take place in a time in which the New Testament church is indeed in existence, like so many previous proofs, there is nothing in this proof that is unique to the New Testament church, and is thus not proof of the existence of the New Testament church.
It must be understood that the New Testament church is a unique entity that has unique proofs of its formation and existence. Many organizations are united and added unto, but that does not make them churches as they have none of the unique characteristics of the New Testament church. Again, even though the verses cited in Acts are about the New Testament church, as a specific statement of proof it falls far short of the standard required to be actual proof.
