Confused on Catholic rituals
I was baptized as a child and after that my famil and I haven't gone to mass much until very recently when I felt that I needed to go back to church. I went to a Baptist church for a while as well and struggled to find out which was the right path for me. I prayed about it and I think I got the answer I needed so I want to go back to mass.
I did some research and I know my mom didn't keep her word to raise me as a Catholic... but she has been going back to church, she just needs the courage to confess and ask for forgiveness?
I'm not too sure on the rituals, but I heard that I needed to be Confirmed/baptized again. Am I still able to do this? And what is the process like?
Also, when one prays, I know that one is supposed to cross from forehead, heart, left, then to the right and say "In the name of the father, and the son, of the holy spirit, Amen." After that, how do I start a prayer? Just... Dear Father? I know this may sound like a really stupid question, but when I went to the Baptist church, we always said, Dear Lord, or Father, and closed it with "In Jesus name I pray." So I was just wondering if there was a specific way to start and close prayers besides crossing oneself.
Thank you all for the help!
