The bishops are urged to enthusiasm for the task presented to them, to draw the laity into the celebration of the Mass in ever greater numbers. I presume also, with great fruitfulness. Let’s read:
201. Above all, try with your constant zeal to have all the faithful attend the eucharistic sacrifice from which they may obtain abundant and salutary fruit; and carefully instruct them in all the legitimate ways we have described above so that they may devoutly participate in it. The Mass is the chief act of divine worship; it should also be the source and center of Christian piety. Never think that you have satisfied your apostolic zeal until you see your faithful approach in great numbers the celestial banquet which is a sacrament of devotion, a sign of unity and a bond of love.[Cf. Saint Augustine, Tract. 26 in John 13]
Catechesis is part of this plan, even outside of Mass:
202. By means of suitable sermons and particularly by periodic conferences and lectures, by special study weeks and the like, teach the Christian people carefully about the treasures of piety contained in the sacred liturgy so that they may be able to profit more abundantly by these supernatural gifts. In this matter, those who are active in the ranks of Catholic Action will certainly be a help to you, since they are ever at the service of the hierarchy in the work of promoting the kingdom of Jesus Christ.
How much did this catch on, I wonder, in the years after WWII? Have we lost something of this verve in the wake of discouragement, liturgy wars, and a modern culture far more indifferent to religion that the West of 1947.
