966 when Poland officially adopted Latin Christianity anyway.
Catholicism is what I think of as a "rich" religion. It has many, many layers and many, many rites/rituals. If you've ever seen photos of the Vatican in Rome, Italy, you've seen how much the Church values art, architecture, and pageantry. There are processions on holy days (kinda like religious parades), feasts on saints' days (not so much banquets as featured specialty foods and "celebrations"), and of course there are the holy days that have entire seasons... Lent/Easter and Advent/Christmas. All of this is in addition to the prayer options... Masses, Novenas, Stations of the Cross, Vespers, Rosaries, et al. which have their own rituals associated with them. Some of these can be observed in a private way but for the most part they are intended to be observed by the whole church family as a group.
When it comes to personal religious rites, the Catholic church has basically seven: Baptism, Holy Communion, Reconciliation (confession/forgiveness), Confirmation, Matrimony, Holy Orders, and Anointing of the Sick. I'm not going to go into an explanation of all seven here but I will touch on how these rites relate to my family's history. If you're interested in learning more about the seven "sacraments", as Catholics refer to them, you will find a basic explanation on Wikipedia.
In "the old days", children were baptized as soon after birth as possible. In rural Poland, that generally meant the same day or the next day. Infant mortality was high so children were baptized quickly in hopes that should they die their souls would get to heaven. Around the turn of the century (1900), when modern medical practices reduced the risk of infant mortality, the time between birth and baptism lengthened. Medical advances happened here in the U.S. before they appeared in Poland. Here are some examples of how that played out in my own family.
All 8 of my great grandparents were born and baptized in Poland...
1843 Szymon Lipa born October 2, baptized the same day.
1855 Wojciech Lisowski born March 26, baptized the same day.
1857 Ludwika Knot born July 6, baptized the next day.
1862 Krzysztof Laska born March 24, baptized the same day.
1862 Piotr Mizera born April 16, baptized April 21, 1862 (5 days, the delay in his baptism was likely due to his being born during the Holy Week preceding Easter, which fell on April 20th in 1862)
1862 Anna Bober born November 13, baptized November 16, 1862 (3 days)
1864 Karolina Furman born March 12, baptized the same day.
1865 Jozefa Adamska born March 2, baptized March 5, 1865 (3 days)
My 4 grandparents...
1884 Wincenty Lisowski born January 18, in Poland, baptized January 21, 1884 (3 days)
1884 Jozef Laska born August 20, in Poland, baptized the same day.
1889 Karolina Lipa born August 1 in Detroit, Michigan, baptized August 11, 1889 (10 days)
Birth and baptismal records are not available for my other grandparent.
1914 Joseph born August 5, in Detroit, Michigan, baptized August 9, 1914 (4 days)
1918 Lucy born July 10, in Detroit, Michigan, baptized July 21, 1918 (11 days)
I was baptized 5 weeks after my birth.
My daughter was baptized 2 months after her birth.
My son was baptized 5 weeks after his birth.
Holy Communion/Reconciliation (These go hand in hand)
I have no records to substantiate when my great grandparents, or my ancestors before them) received First Holy Communion. However, my understanding is that before 1910 (in the U.S., anyway) children were confirmed at the same time they received their First Holy Communion (see here). I have seen the Confirmation Book at Sweetest Heart of Mary Church and found my grandmother, Karolina Lipa, among those confirmed in 1910. She would have been 11 years old at the time. I had a brief conversation with the Pastor of the church and he told me that back then the children of the parish did receive their First Communion at the same time they were confirmed.
From about 1910 on, children have received the sacraments of First Holy Communion and Reconciliation at about 7-8 years of age and Confirmation at about 12-14. That's here in the U.S. I don't know at what age these sacraments are administered in Poland.
Here in the U.S., making one's First Holy Communion is cause for celebration. I'm not sure if I have more First Communion photos in my collection of family photos or wedding photos. It's close. First Communions in the Polish community (and in my family) were usually celebrated with big parties, gifts, and a trip to the portrait studio. I have more First Communion photos than vacation, birthday, graduation, Baptism, Confirmation, or Christmas photos. Girls always wear white dresses with a veil. Boys wear a suit and tie. It's a big deal.
I don't know a lot about the Confirmations in my family. Confirmation wasn't celebrated the way First Holy Communions were. I don't even remember a lot about my own Confirmation. It was performed by a Bishop as opposed to a parish priest (Confirmation always is). I wore a fancy pastel dress. My cousin Marlene was my sponsor. And I chose the name, Barbara (you always get to pick a new name). I was 13 years old. I don't remember any parties or gifts or even going out to dinner. That's all I remember.
I have a gazillion wedding photos in my collection of family pics. I'm pretty sure that all of my ancestors in Poland were married in a church wedding. I don't know if civil wedding ceremonies even existed in Poland in days of old. Many of my family members here in the U.S. were married in the Catholic church as well, but not all of them. My grandparents, who were the first immigrants to the U.S., married at Sweetest Heart of Mary Church in Detroit. Some of their children married in the Catholic faith but others chose to elope and have civil ceremonies. I have many wedding photos of those who married in the church, none for those who married in civil ceremonies.
This sacrament is reserved for those who become priests, deacons, and bishops. To my knowledge, there is only one priest in the family. My second cousin Pawel, same age as me, is a priest in the Cathedral in Łódż, Poland.
Anointing of the Sick
This sacrament is performed by a priest at the bedside of someone who is gravely ill. Both of my parents received this sacrament. I'm not sure how many other of my relatives did. Those who died suddenly and unexpectedly would not have received this sacrament, only those who would have been gravely ill and had time to request the audience of a priest would have.
I would say that Catholicism and the rites and rituals that go along with it are the fabric of my family history. The location of the church may change, the individuals involved certainly did, the timing of the rites did as well, but the rites themselves really hasn't. Not since long before records were kept for such things.
