I think the CC teaches people that this is talking about the priesthood, but imo, I think it means ALL of us, but I think the CC does not want to tell its followers that they must actively go out and try to convert people, like many other religions do.
I know alot of catholics and have many good friends that attend mass regularly, but I have never seen one of them actively trying to convert strangers, and/or bring up the topic in social settings in an attempt to get someone interested, the most Ive heard any catholic say is an invite to mass, but that is about as far as they go in their attempt, BUT when it comes to other religions, I have come across some very good talkers, almost like salesmen, trying very hard to get someone ‘saved’ or at least a promise to join them at church.
Most of the catholics I have seen and know dont seem to be overly proactive in converting strangers. I really have alot of respect for Pentecostals, I know quite a few of them as well, and nearly all of them are very proactive in trying to convert people, they will go up to complete strangers, give them their church address and invite them, start talking to them about the bible, God, etc. It is amazing to see how devoted they are, not just the Pentecostals either, Ive seen a few other denominations doing similar things.
