I am a living witness that through charity my family’s behavior got better. All those who were kind and tolerant of my noisy children helped my son to get to a place where he is very reverent of the Mass, and he is only 4 years old. My 2 year old son is still on the way. He is improving.
It may be true that the priests that you know do not appreciate noisy children being present, but there are other priests who feel the opposite way. This includes the pastor at my grandmother’s church, who forbids removing them, and also the pastors at my church, one of whom once said in the middle of Mass, “I love the sound of babies in church.”
I am grateful to them for their charity and their willingness to work with families and their ability to show us that we are all loved.
I think that the way to lead those who are struggling in the right direction is through prayer, and kindness, and perhaps by letting a person see our sorrow at the situation, which is doubtless difficult for everyone- but not by criticizing others during Mass.
Jesus taught us to examine our own shortcomings rather than focusing on those of others. If we cannot follow His teachings at Mass, where can we?
