Question:
Is it okay to use Soncino press?
Are they considered heretics?
Some of their books have Christian commentaries?
Answer:
I can not comment on all of the books as a whole, when I don’t know all of them. Books that contain commentaries of heretics may not be used. In general there are other very fine printing presses that publish many fine seforim, that you don’t have to get involved with controversial things.
Best wishes
