There were and are things from the early to mid 20th century Catholic culture worth preserving, bringing back, and passing on. Certainly the ritual and splendor of the Solemn High Mass in Latin would be a prime one. Regular weekly devotions like Our Lady of Perpetual Help and Friday Way of the Cross, both with Benediction would be another.
Many of the Old Hymns, some in Latin and some in English were beautiful and uplifting to sing and to hear. Also reverence, and respect for things and persons, seems to have been unfortunately forgotten.
The practice of frequent Confession, say every two weeks would be another, but the intense emphasis on man’s total depravity and sin riddled lives I can do with out. Not that sin should be ignored or not discussed, but that the off-setting graces and love that the Lord has for his creatures should accompany that concern and discussion. I do believe that today we have become unbalanced in the opposite direction. Nobody wants to talk about or admit that we are prone to sin.
The other thing better left in the past was the fear of becoming contaminated by associating with non-Catholic people and the prejudices that accompanied that fear. What I would like seeing with a renewed emphasis would be the idea that it is best to marry your own. That seems to be a consideration that has by and large gone by the boards on both sides of the fence.
There were also a lot of ethnically related devotional practices and special food items associated with the feasts of the liturgical calender that are being lost. That too seems to be sad.
Last but not the least, a practice that I am happy to see gone, was the notion that no matter what, one must check with “Father” before making a decision on even the most mundane of questions
So I guess it is a mixed bag. Some parts of the culture are worth retaining and others are gone and good riddance…
