345. Having given a summary of the things which go to make up spiritual faith, I shall now give too a summary of the things which go to make up purely natural faith. This is essentially a firm conviction which pretends to be faith, but is a conviction of falsity, known as heretical faith. Its various types are: (1) Spurious faith, in which falsities are mixed with truths. (2) Meretricious faith coming from falsified truths, and adulterous faith coming from different kinds of adulterated good. (3) Concealed or blind faith, which is faith in mysteries which are believed in, despite ignorance whether they are true or false, or whether they are above the level of reason or contrary to it. (4) Erratic faith, which is in a plurality of gods. (5) One-eyed faith, which is in some god other than the true one, and in the case of Christians in a god other than the Lord God the Saviour. (6) Hypocritical or Pharisaical faith, faith, which is a faith of the lips, but not the heart. (7) Imaginary or upside-down faith, which is falsity made by clever arguments to seem like truth.
