It is customary to put many honorific titles before most modern day Rabbis (I've even seen seforim that write Harav Hagaon etc. etc. So-And-So). Many times one sees long lines of adjactives praising the Rabbi being quoted.
Yet, we refer to most of the earlier Rabbis with much less adjectives. I've never heard anyone say Harav Hagaon Rashkebehag Kvod Kdushas Moshe Zatzal when referring to Moshe Rabbeinu.
Is it that we have more respect to our Rabbis than they did in the past?
