Some orthodox Jews have criticized Rabbi Greenberg and questioned his orthodox credentials. After Greenberg came out, Rabbi Moshe Tendler, Rosh Yeshiva at Yeshiva University stated: "Being an Orthodox Rabbi and actively gay is an oxymoron ... is the exact same as if he said, 'I'm an Orthodox rabbi and I eat ham sandwiches on Yom Kippur'. In Tendler's opinion "it is very sad that an individual who attended our yeshiva sunk to the depths of what we consider a depraved society" and called Greenberg "a Reform rabbi".
