Ad insidiosum Lucae Osiandri scriptum

1 Cor. 10.

mentioned saying of Paul—namely, that the Fathers ate his flesh even before the incarnation of Christ—must be erased. But because these things are true, you perceive, dearest brothers, how inept Osiander's argument is.

Another [argument] follows, no less invalid than that one, and yet repeated by him in almost infinite places, both here and in the book against Sturmius.
