VERY good point. I often say that I wish many of these former Protestant ministers who have joined the Catholic Church would serve us VERY well as deacons. Their preaching skills and devotion to Christ and the teachings of His Church could be a wonderful asset. Deacons MAY preach the homilies at Mass, and while it is not the focal point of our wosrhip - the Eucharist is - to hear an orthodox well preached homily is always a blessing.
In all the discussion of the “vocations crunch” in the US we often overlook the 15,000 deacons we have ordained in the past 40 years. (The program has only recently in the past decade or two become available in some places!)
NO, these guys are “half priests” They have a distinctive ministry seperate from that of the priest, while still sharing in Holy Orders. BUT they can and do play an intregal part in bringing “Christ to the World”.
Pray for more priests certainly! But do also pray for more deacons!
