The bounds of the discussion would assume that it is obvious that the Reformation Church is the same as that of the Apostles...
What "bounds of the discussion"? Why should there be bounds? Why not examine the teachings and practices of the churches of the Reformation (There were several of them), and compare them with the Apostolic Church?
1. The Apostolic Church met in houses (Rom 16:5, I Cor 16:9, Col 4:5, Phm 1:2)
The Reformation churches met in big, fancy church buildings or cathedrals, following the example of their mother, the Catholic Church.
2. The Apostolic Church had a body ministry, that is, each member of Christ's body, ministered to the others (1 Cor 14:26)
The Reformation churches had a one-man ministry,following the pattern of their mother, with an altar at the front, directed by one man. There was only formal participation by the people, singing hymns together or reciting creeds.
3. The Apostolic Church wrote against heresies (2 Peter 2:1).
The Lutherans and Calvinists put heretics to death by burning them at stake or drowning them, again following the practice of their mother church. They even put to death the Anabaptists as heretics, whereas in fact, the Anabaptists comprised one of the Reformation Churches.
No, the reformation churches were a far cry from the Apostolic Church. The Catholic Church was at least a gradual development away from the Apostolic Church, whereas the "reformers" were revolutionists.
