He was evidently speaking at an ordination for transitional deacons.

From CNA: 

The archbishop of Valladolid, Spain, Luis Argüello, called it “revolutionary” in our times to make the supernatural present in the streets by wearing in public the clothing proper to consecrated religious or ordained men.

The prelate gave this reflection in his homily for a diaconal ordination, noting that the deacons will wear specific vestments.

“You are going to wear clothing proper to you. A diaconal stole and a dalmatic will be placed on your alb. And you can also wear clerical dress, you can wear a symbol so that it can be seen in the public square that you are men consecrated to the Lord,” the archbishop explained.

“There was a time when the novelty appeared that had to do with our taking off the cassock and the Roman collar. Today there is a time in which surely what is revolutionary, novel, the presence of the supernatural in the streets and squares, is friars wearing a habit, nuns being recognizable, and those of us who have been ordained also being recognizable,” he added.

The archbishop also considered the promises made by deacons at their ordination to be “revolutionary.”

“Brothers, what these friends are going to promise today is a revolutionary novelty that our world needs,” the prelate said referring to the commitment to pray the Liturgy of the Hours, to be celibate, and to obey.

Argüello explained that praying of the Liturgy of the Hours ensures that “in the Church from morning to night, from sunrise to sunset, the name of the Lord is praised” and warned that “without praise the heart shrinks and without praise the hands close.”
