<div>Both R Micha and R. Zev provided arguments that metzitza is integral to the performance of brit milah. But nothing either has written indicates that metzitza b'peh is the only mandated method to accomplish metztitza. Unless that is so, then the question remains, if the mandated metzitza can be accomplished in a way that eliminates pikuach nefesh concerns, what is the justification and/or the source requiring metzitza b'peh in light of the possibility, however remote, of fatal consequences?</div>
