Yes but it’s using a secular term because it’s a simple (even if not entirely accurate) description. Granted, it’s not like any sort of secular role - there are no set number of “positions” to fill and it’s not a job it’s a way of life!
Of course, the Holy Spirit must necessarily play a major role in the process, but having said that, we too have a part to play since the Spirit works through people. So, I guess what I’m getting at is that we can’t just sit back and say “well the spirit will sort it”! Certainly the spirit does prompt (and sometimes even shove) men towards the path to priesthood but, at the same time, discernment isn’t a solitary activity. Just as the Church has a role to play in recognising vocations so too the community has a role in encouraging them. Obviously, it’s important that we pray for vocations and that parents and priests talk about it generally. Beyond this however, IMHO those who are actively discerning a vocation to the priesthood need to be provided for especially considering that discernment can be a difficult, lonely and daunting experience.
So what does my diocese do? Well, actually little if anything. There might be the odd, dated and slightly faded poster around on a few parish noticeboards but that’s about it. In days gone by we had a group for general discernment of vocations (i.e. not just priesthood) which met regularly, along with another group just for those discerning the priesthood. This was something which I found really helpful in my discernment and really wish they’d revive it but that’s not something i see happening any time soon sadly.
If I had my way, this is how I’d do things: ukvocation.org/
