In Christianity, priests generally do not meditate. Often, the sole role of a Catholic priest is to preach the religion to devotees.
In Asian Buddhism, the role of many monks is similar, which is why they devote most, if not all, of their time to teaching & conducting ceremonies. There are even Western monks, in Asia, that mostly teach & translate.
While I have never read it myself, I have heard the Buddha stated that monks who primarily meditate should not criticise monks who primarily study & teach. If this is true, then the dichotomy between 'meditation monks' & 'study/teaching monks' goes back to the time of the Buddha. A good example is Venerable Ananda, who often gives the impression in the suttas of not being a particularly adept meditation practitioner.
In my monastic experiences, I have not observed any correlation between teaching & practising the eightfold path. Often it is those that are seriously practising the eightfold path that do not teach.
There are highly reputed monks (eg. Ajahn Jayasaro) that spent many years as a (highly reputed) meditation monk before teaching extensively to the public.
