I read this great article by Father John McCloskey :
Here is a start to the article...When I was a young man serving Mass at my local parish, I was struck by one particular priest who was resident in the parish. He was a veteran of the Second World War and a trained lawyer and at that time the editor of the local diocesan newspaper at a particularly difficult time, after the issuing of “Humanae Vitae.” This would have been just after the Second Vatican Council when there was much confusion regarding the liturgy, priestly identity, and the role of the laity. This priest, I noticed, always remained after the Holy Mass for some time to give thanks, was meticulous in the care he took with particles of the Host that might accidentally have fallen on the altar or on the floor during the course of Holy Communion. I also would often see him praying before the Blessed Sacrament in the Church. Many years later, I learned that he was a priest of the Priestly Society of the Holy Cross and that, at least in part, he had learned these fine details of priestly piety towards the Eucharist from the example and teachings of the Founder of Opus Dei.
As Saint Josemaria put it:
“We are not going to do an irreverent genuflection, like the soldiers did before Christ. We are going to adore! The people notice everything and they will think: my priest, how he loves Jesus! How clearly he knows that he is in the Sacred Host! If they only see you on your knees before the Lord, you will win over their souls. Don't exaggerate but work within the ecclesiastical law putting there your heart and faith. (get-together with priests 10/31/72).”
“A priest's worth can be measured by the way he lives his Mass.”--St Josemaria
