The "link" is a Faith and Practice which goes back to: the shores of Galilee, The Book of Acts and Jude 3, through the gates of Hades, not re-re-reformed pedobaptists. It is not about a name.
The reference to Calvin's persecutions is to show that his heart of hearts was like Rome and the other daughters of Rome--i.e. given over to strong delusion, believing a lie.
Forgive them for sure, but do not let them in the fold without true fruits of repentance. Anabaptists seriously screened candidates and baptized them scripturally on proof of repentance. Of course this would incense a pedobaptist cleric of any flavor.
The daughters are going back to Rome. Now what? We know not what persecution is about. Read: Sam Morland, "History of The Evangelical Churches of the Valley of Piedmont."
Even so, come, Lord Jesus.
