If one rav paskens something is Asur Deoraisa and another Paskens totally mutar, beshas hadechak is it better to get a non-Jew to do it or a Jew whose rav holds its muttar?
For example, if a certain city has a machlokes on an eruv (where the tzad isur holds deoraisa) and a mohel forgot to bring his knife to a baby's house for a milah on shabos, is it better to get a non-Jew to carry the baby/knife or for a Jew who carries to do it?
Other examples of such situations are welcome in the comments.
