All I can speak of is how it was handled in Oklahoma which I attended from 1951 until 1980 . After Vat 2 ended, I remember the priest talking in his sermons for several weeks that there were changes in the air. Most of us didn’t give it much thought—after all, how could they actually really change the Mass, a litany we all knew by heart in Latin or church traditions? Then, I went to Sunday Mass and suddenly a second altar stood in front of the old altar where the priest had always stood. The tabernacle stayed on the old altar-- no tabernacle was on the new one. I remember thinking the new altar was an eyesore. A week later, they introduced a new English liturgy. Suddenly, organ music was replaced by guitar liturgical songs–all unfamiliar. Also, the communion rail where people knelt and received the host on your tongue was replaced by a priest handing you the host. Everyone drank from the same chalice. Before Vat2, you received communion under 1 species. Altar boys wore cassocks-not street clothes. The liturgy was different too–words to many previous Mass prayers were absent or different. In their place were a"Cliff Notes" version–all in English! They changed this back now, but pre V2 the priest said “Dominus vobiscum” ( Lord be with you). The reply was “Et cum Spiritutuo” (And with your spirit). Post V2 all answered “And with you also.” Post Vat 2 they added the protestant version of the Lord’s prayer–“For the kingdom, the glory are yours now and forever”–to the Catholic one. People were hauling baskets of donations up front at the offertory and instead of a hymn, a dance troop up front, swayed to a Christian-rock hymn. Before, if a female entered the church without a hat, a nun would slap a kleenex on your head where the hat belonged. All at once, rules stopped. People were okay coming to Mass in cut-off shorts or whatever they wanted to. Once we fasted 2 hours from solid food, 1 hour from liquids before communion. After V2 you didn’t have to fast. My daughter received 1st Communion after V2. Before we spent months of catechism before our 1st confession and communion. It was a big deal. Little girls wore white dresses and veils. Boys wore white suits. Most girls were got a “1st Communion purse” containing a new rosary and Missal–and we were very proud of them. 1st Communion was a BIG deal-- candidates marched in together with pomp and set in the front pews. Older kids–were angels–escorting candidates a row at a time to the communion rail to kneel. You got it that something very important was happening. We couldn’t chew the consecrated host or let it touch our teeth. When my girl made her 1st, there was no classes. Parents decided when your kid was ready. You took your child to confession when you decided to.Suddenly, kids made 1st Communion by walking up front with their parents whenever they chose. I was told “No white dresses”–only street attire. It was a difficult time for many of us who loved the “old way”. Suddenly we barely recognized church anymore. Many people loved the change but just as many hated it and felt that the Church had traded something solemn, beautiful and mysterious for a Mass resembling a protestant service. My husband–a convert–loved the new songs and English Mass. I hated it and felt a bit like my Church sold out, Changes in the liturgy, nuns wearing street clothes and everyone coming to church casually dressed with bare heads, was a real turn-off to me. I “fell away” for 30+ years. I have been “home” i for about 2 1/2 years now. I place no blame on V 2, these days. I don’t resent the priests, Pope or anyone who decided on changing things. I now only blame me for my falling away. I regret it deeply. None of my children are Catholic now. Most of my grandkids haven’t even been baptized. By falling away I failed my children. Personally, I don’t feel that all the changes made all at once were an improvement. Before V 2, everyone treated Mass and the sacraments with a deep respect. Now , not so much. Everything today is PC and casual–not dignified and special I am an old lady and that contributes to my personal preference for most everything pre-V2! At the time of the changes I was in my late 20’s. The changes sort of scandalized me… I felt that if they could change the heart of Catholicism–Holy Mass–that nothing was sacred anymore. I began to doubt my entire faith. Many may disagree with me–my own hubby would–but I think when and if the Church changes things again, they should REALLY think about it for a longer period, introduce change slowly bringing parishoners aboard over extended time so nobody is shocked or offended by upheaval. Now I have adjusted and accepted “new” and am sorry I wasn’t adult enough back then to see past changes and realize it was the same Mass. Jesus was in the Eucharist and it was the same Catholic faith which superceded humans beings dreaming up up changes. I paid a heavy price for blindness as a younger woman.
