Maculata?

I asked my pastor if Lutherans held to the Immaculate Conception and he said that it was sort of a pious belief (which Luther held originally), and I was content in that, but after reading St. Bernard's immaculate(?) case against the Immaculate Conception... I'm not so sure

In any case, like St. Augustine, out of reverence for the Mother of God, I will make no speculation as to her sinfulness.
