I was approaching  my 17th Birthday on the First Sunday of
Advent 1964 on November 29, 1964.
This is when the first changes took place such as the
abolishing the prayers at the foot of the altar, and
abolishing the last Gospel. A layman was allowed to read the
Epistle, and in some churches, the table was placed in the
Sanctuary to offer mass facing the people.
I was lucky, the small Parish I was attending in San
Bernardino,Ca. Still offer the 1962 revised Mass because there
was not new enough liturgical books to go around. I was spared
the changes into early 1965 when my priest received the
new liturgical books, but was hesitant to use them. A
liberal faction wanted the mass to be celebrated in the new
way. However, there was a faction in which I belonged to
want Mass said in the traditional way.  This is when factions
over disagreement on the Liturgical changes, and later
spread to other areas such as church teachings, and
discapline. A compromise was made that new mass was said at
9am, and the Traditional Mass said at 11:15AM. Today, this
Parish is thoroughly Novus Ordo Cafeteria pick, and choose catholics. I never notice any factions of Catholics fighting
among themselves until the liturgical changes. If Liberal,
and Conservative, we never questioned Church doctrine, and
teachings. It was unheard of among the laity in up to that
First Sunday of Advent 45 years ago. This is when Catholics
started to take sides. One side saw changes that were not
even desired 6 months before, and wanted more. And a
Traditional Faction whom wanted things as they were.
The results have been a great falling out of Mass attendance,
and a decline of belief of Church Teachings, and Doctrines.
Vatican 2 changed many of the Traditional teachings of the
Church, and if you are a Traditional Catholic, you just cannot
attend a Novus Ordo Church. Instead fulfilling Mass
obligations at St. Pius X and other  Traditional Catholic
chapels.

About 1969, I was entering St Matthew's Church, The
Cathedral in Washington,DC. There was in the crowd Young
Women about my age making fun of an elderly women
because she was had a old missal she was bringing in to
the new mass. The memory of this has been burned into
my conscience,

I lived, and worked in DC from 1966 to 1970. My Parish Church
was St. Dominic's, operated by the Dominican Fathers, and
Brothers. I served Mass there.
I remembered at that time, there was a High Mass sung in
Latin at St Matthew's in the Traditional Rite.
Other Parishes offered the Old Mass in Latin in the DC area.
All offered on the table facing the people.
I always attended Mass of Father Gomer DePaul when he
came to town.
I returned briefly in 2003, and revisited my old hauntings
that are mostly intact.
