I am a 4 year old Catholic...but really can't say that I converted since I'd never belonged (read been baptized) to any other church. DH is a cradle Catholic and I started attending mass with him a few months after we started dating in 1997. I had been to services at many different churches (i.e. Lutheran, Methodist, Mormon, Pentecost, Charismatic, Baptist, etc.) throughout my life...what I've always called "church shopping". I found DH's parish to be very warm and inviting...everything I knew about the Catholic church was intriguing, I admit, but it was the peace I found there that really drew me.
I began instruction (RCIA in September 2000, which involved weekly classes, attendance at mass, and discussion about the liturgy. The part about needing a sponsor is correct; you need an active member from the parish to sponsor you...I thought mine might be my future MIL, but the RCIA team told me someone who wasn't family was preferred, so I asked my future MIL to be my Godmother and another woman from the church was my sponsor. They both attended RCIA with me for the second two thirds of the classes.
RCIA has 3 main parts, the first is more general (IMO), then the second is when you receive a sponsor and are introduced to the parish family, the third part is when you become a Catecumen (not sure if I spelled that correctly...I'm still working on all those Latin words). At the beginning of this portion, our RCIA class went to the Diocese with all the other RCIA participants and declared our intentions in front of the Bishop...it was a very moving service. After completition of instruction, at the Easter Vigil, which is the only time an adult may become a member of the Catholic church, and is also the highest of holy times in the church you become a member of the church. In my case, I was baptized, received confirmation and first communion (eucharist) at Easter Vigil.
For me, personally, there were other factors involved in my "conversion". My mother died in September 1999, and struggled with the fact that she did not have me baptized as a child...she thought she had failed me. The morning before she died, I spoke to her at length on this subject despite her being in a "non-responsive" state I know she heard me. I know that she did not fail me, but rather gave me the best opportunity...to find my path when the time was right for me. Additionally, when DH and I began to talk about marriage I knew that I wanted us to be married in the church and having been previously married I knew that I would have to have that marriage annulled by the Catholic church. So, while I was in RCIA I completed the paperwork needed for that and prayed that it would be granted. I wanted to be able to partake of the sacrement of marriage in the same capacity as my future husband...with a full nuptial mass. The annullment was granted and DH and I were married with the full rites of the sacrement. I also have a child from that previous marriage, who has not been declared illegitimate because of the anullment and we included him in our ceremony. Now, DS has at times expressed an interest in becoming Catholic, but he too will have to go through instruction (RCIA since he's 13 now), but IF he choses to do so, he will only receive confirmation and first communion as he was baptized as a Lutheran when he was a baby. (It was his biological father's denomination.) I was able to have DS's membership from his grandmother's Lutheran church switched to our Catholic church, so he's still a part of the parish family even though he's not Catholic.
Well, now that I've said quite a bit on this topic, I will just add...
- You may be able to participate in the RCIA classes (first portion) without becoming Catholic (if memory serves me on this)
- Those comparative religion classes may or may not offer you the assistance you are looking for. I say this because I'm currently interpreting in a World Religions class and it's listed under the philosphy department and it really is more philosophy than anything else...so check into the class before you spend the money.
- IF you do decide to convert, be sure you are doing it for the right reasons...the Catholic church has some very different opinions about matters than other Christian groups.
- If you just want your children to go to Catholic school...as other posters have said, they don't need to be Catholic...it just may cost more and there may be some other aspects...just check with the Catholic school system you are interested in sending your children.
