Martin Luther

“ Therefore, I beg that you do not make yourselves partners in another’s sin. You have enough to do to pray to God that he would be gracious to you and preserve your rule as I still pray daily and hide myself under the protection of the Son of God, whom I hold and honor as my Lord. ”

“ If not, then we would not permit them [to live among us] , for Christ commands us to be baptized and believe in Him. Even though we cannot now believe so strongly as we should, God is still patient with us.
Now, here is what the Jews do: daily they only blaspheme and dishonor our Lord Jesus Christ. Since they do this and we know it, we should not permit it. Should I permit anyone to be with me, who dishonors, blasphemes, and curses my Lord Christ, I make myself a partner in another’s sins [1 Timothy 5:22] . I have enough sins of my own ”

“ They can also practice medicine as in French Switzerland. They administer poison to someone from which he could die in an hour, a month, a year, ten or twenty years. They are able to practice this art. Therefore, do not be involved with them as with those who do nothing else among you than heinously blaspheme our dear Lord Jesus Christ and deprive us of body, life, honor, and goods.
Yet, we will show them Christian love and pray for them that they may be converted to receive the Lord, whom they should properly honor more than we. ”
