As I am approaching the completion of gerus, HaShem has brought me a new wave of challengers. Old friends who were drawn to Christianity have began contacting me. A conversation was initiated about a point or two about the Tanakh, which one grossly misunderstood. So I begin spending time responding to some of his claims using Torah sources.
I remember an injunction in the Torah that Jews should know how to respond to heretics, which Christians admittedly are not. As far as I know, heretics have to be Jewish. Christians are mainly gentile idolaters according to Rabbi Moshe Weiner's Divine Code.
I can win these arguments but I fear that there is a prohibition to speak to them. I read from an earlier post here that poskim ruled that we are not allowed to teach idolaters Torah. What are your thoughts on what I should do? Should I ignore them and move on with my life or get the last word in and eliminate all accusatory doubts.
