That is a great question. I ponder it. When I came from the New Order in 1996, I went through steps. I wanted to know what it is to "be" a catholic. My great-great uncle was/is a priest of the Confraternity of the Precious Blood. He went to school at St. Charles Seminary in Carthgenia Ohio. A priest from 1905 to 1944. So, I have asked him through prayer to help guide me what it is to be a true Catholic. I wanted to know what was in his "noodle". What he had learned.
So, I found a new excitement for my faith, with his help. Fr. Faber, Fr. Nagelisen (sp) the book of the Charitable Souls. I found that I want to learn to be a Catholic. I am excited and proud to be a catholic. I must know the teachings and know enough to defend the Catholic Faith. It is an inheritance. For those who become lazy/sloth and don't care about being catholic anymore, I see as very sad.
I will let strangers know that of all the roots that we do looking into our past, our Catholic faith is the most beautiful of inheritance. So, I took time to look into the roots of my great=great uncle Fr. Rudolph Stoltz. I was blessed to be able to walk through St. Charles Seminary in 2000 with my mother. I saw Fr. Stoltz's tombstone. I walked through the halls, he walked through. I asked the tour guide(was priest) to show us the chapel/altar. I knew it would be gone. It was. It did not affect my mom, but it did me. My mom is new order. I showed my disappointment when I saw it was gone. Side altars went to the basement, where priest say new order mess.
I spoke up to the tour guide, my mom was upset with me. I was hoping my mom would see what I see, but she couldn't/wouldn't. My mom was so made with me that she said, "Why do you think you know so much!" "All I want to know is why Fr. Stoltz wanted to be a priest." So, I said, "We will pray and find out". The prayer was answered!
The next year, my mom found a letter from Fr. Stoltz dated May 28, 1905. That date is my mom's birthday, May 28. She shared the letter (falling apart) with me on her birthday! Fr. Stoltz's letter began: Dear Herman (his nephew, my grandfather) I understand you will be receiving your first Holy Communion. Oh, the most beautiful day of your whole life.... Pray for your vocation. It was on my Holy Communion day, that I prayed and I got a strong inclination to study for the priesthood!
The letter was longer. He said, "At the top of this letter, you will see a picture (ink stamp) of St. Gaspar, the founder of the Precious Blood confraternity and Pope Pius X just saw to him being Blessed.
This is the excitement that helps me with "what it is like to be a catholic". I did more work with the roots of the family. My great-great uncle was age 5 when he left Bavaria with his family in 1847, one year after the 1846 letter of the Pope stating Communism for all it was. In 1846, a potato famine that happened. With more reading I read of war, and catholics being hated. Gov't telling them to immigrate to the US.
I am proud to be a Catholic and I thank God for my inheritance and I pray that I can be strong as those who are martyrs. The Spirit is strong yet the flesh is weak.
It takes work to work for God and the whole heavenly cohort. Prayers are so important. Rosaries and sacraments. The Power is in the Blood, which is in all the sacraments.
