My advice is this: study the two issues, then go talk to a priest (parish priest or a priest you find comfortable with), discuss the issues that bothers you and use some time to think and reflect this through.
I did this myself and spent four months thinking before deciding to convert. Today, i fully understand and support the things i had issues with. It was a wise move i think.
So to all candidates of RCIA classes:
- Take time, study, read, pray and be happy.
- Talk to a priest if you got issues.
- Attend mass (i recommend 2x a week as a minimum).
- and most of all: trust the Lord. Not a bit, but totally.
It will help and you will also learn a whole lot from it.
I wish both of you the best of luck.
God bless.
