If the Catholic Church is that antichrist of John Calvin et al, then Martin Luther would have been a dead man this side of heaven. As it is, Martin Luther declined an invitation and his life and limbs were unmolested by the Church after he declined. Your apologies may be deposited in the offerings basket on your way out.
As I said, he read Matt 2 and declined his summons. Jan Hus indeed. More a statement of the loss of secular power than good wishes from the Catholics.
