I am a middle aged man who returned to the faith in the last few years. What I find unacceptable and/or inappropriate in (before and after as well) the Mass are:
(1) Loud fast-beat music, or sentimental feel-good songs with no traditional religious meaning or depth,
(2) Noise, talking, commotion in the congregation at any time,
(3) Revealing and tight clothing,
(4) a lack of spoken prayer (too much singing)(I think some attend solely for the musical performance. I have even heard clapping at the end of a Mass and it was not for our Lord!),
(5) alteration of the true gospel language and thus the meaning (inclusive or “correct” language substitution),
(6) “modern” practices like holding hands at the Our Father or introducing ourselves to others before the Mass,
(7) a lack of reference to sin, Hell, and damnation for fear of offending parishioners (those of us who love the Truth want to hear the blunt reality),
(8) Common parishioners walking around or at the Holy Alter (they often do not even have the sense to bow or genuflect) ,
(9) Common parishioners handling the Eucharist,
(10) Alter girls,
(11) a lack of male involvement/participation. At times, the Mass seems more like a New Age festival than a traditional Catholic ceremony.
The lack of solemn reverence by the congregation in many Masses and lack of instruction or direction by most Priests in this regard is appalling and discouraging. Do so few understand in Whose Presence we gather and why? I will continue to search for the traditional (real) Mass and the more traditional, the better!
