Those of us who don't want the Mass to turn into a circus or carnival like the rest of society prefer the reverence and respect of the traditional Mass, which does include implicit rules of comportment.
I will never participate in a Roman mass myself, but I can sympathize with your desire for reverence. However, when do all the rules become “commandments of men.” As I read this piece all I could think of was the first portion of Matthew 15 regarding traditions and commandments of men.
1Then Pharisees and scribes came to Jesus from Jerusalem and said, 2“Why do your disciples break the tradition of the elders? For they do not wash their hands when they eat.” 3He answered them, “And why do you break the commandment of God for the sake of your tradition? 4For God commanded, ‘Honor your father and your mother,’ and, ‘Whoever reviles father or mother must surely die.’ 5But you say, ‘If anyone tells his father or his mother, “What you would have gained from me is given to God,”a 6he need not honor his father.’ So for the sake of your tradition you have made void the wordb of God. 7You hypocrites! Well did Isaiah prophesy of you, when he said:
8“‘This people honors me with their lips,
but their heart is far from me;
9in vain do they worship me,
teaching as doctrines the commandments of men.’”
God does not care about comportment. The lifting of hands to praise God is what the first Christians did when the Holy Spirit came upon them: “Therefore I want the men everywhere to pray, lifting up holy hands without anger or disputing.” (1 Timothy 2:8)
God cares about what’s in the heart.
