Reb Eliezer, how does that work when one learns from a heretic (say Reform, Conservative, or Open “Orthodox”)? If one has learned one letter from one a the above then this causes problems.
For example, if one refers to Avi Weiss (the creator of Open “Orthodox”) as Rabbi Avi Weiss (including other YCT graduates), then are we not giving credibility to the Open “Orthodox” movement in the same manner as if one were to daven in a Reform place?
