"And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it" Mat 16:18
How do Protestants explain the continuity of the Church as promised to Peter (and the disciples, presumably), that "the gates of Hell will not overcome it", when the Church seems to have faced a serious rupture, assuming the various Protestant sects are true. What kind of continuity does Luther or Calvin have with Thomas Aquinas or Anselm, for instance? Were people in the middle ages saved through the sacraments of the Church and their faith, such as they had it? If so, why the need for schism?
