When I take Holy Communion to the sick I always wear a stole under my coat or jacket, as a priest or deacon is supposed to. I hate those piddly little ribbons, I wear a normal stole.
A few weeks ago taking Viaticum to someone, two Anglican clergyman approached me, noticed the stole at my neck, smiled, made the sign of the cross and both knelt side by side on the kerb until I passed, one was saying "Benedictus qui venit in Nomini Domini".
A year or two ago the ends of my stole had fallen out of my pocket and were dangling around my knees, I hadn't noticed but a down and out Glaswegian had, he was selling the Big Issue, he fell to his knees and bent his head. I took communion to the sick person and on my return spoke to the man. He said to me, "Sr Marie Louise she always told us when you see a priest wearing a white thing over his shoulders, he is bringing God to a poor dying person, possibly for the last time, and we are supposed to kneel down, and we are supposed to pray, aren't we Father?" I know for a fact he hasn't been to Mass in 40 years.
Occassionally the spouse or a family member will still greet one at the house door holding a lighted candle, a laudable practice.
Compare and contrast this with the lack of preparation one often finds with the practising sick themselves, who are so often more concerned to give you a cup of tea than to express devotion to their Lord and God.
No matter how much catechesis we might give, it is meaningless if we haven't taught devotion.
