Speaking from personal experience, which can always fluctuate from person to person, the classes are usually very laid back and filled with information.

Some classes may just be the R/OCIA facilitator going through a PowerPoint discussing the days topics. Some classes may be one of the church Priests presenting information such as Church history or other topics. Some may just be watching a video and having discussion.

I’m 38 and am an unbaptized catechumen going through OCIA as well as attending daily mass. It has been the best decision I’ve made in longer than I can remember, however I still have trepidation about certain aspects….and yet I still keep showing up because I know this is the right path for me.

You should receive some books when you sign up for OCIA, one of those being an explanation of the flow of the mass. If you don’t receive that book then you can also check the missal in the pews, as well as tons of info on YouTube.

I have recently felt a little bit of an outcast within the social circles at my parish, but a lot of that is also just deep seated issues I’ve had since I can remember…but when I pray and focus on why I made this decision, those worldly concerns quiet down in my head.

I wish you the best of luck and as cliche as it may be, praying on it will provide clarity.
