A couple months ago after converting back to to Church, I went to my first confession. It does take a lot of humility to do so and it was extremely difficult. I put off doing it for so long, because of my pride, I thought, why do I need to confess my sins to a priest? In addition to that I was ashamed of my sins and I didn’t want to even face confession.
Who really wants to bare your true self, it is extremely hard to do. Going to confession means that you have to face up to your sinfulness and no-one wants to do that without the grace of God. It is so easy just to lie in bed, or go to your closet and confess your sins directly to God. This takes no real effort, humility or real submission. That is why it is so tempting to do so and to say that is how it should be.
The Bible says we should confess our sins to one another, and that Jesus gave the power to forgive sins to his Church. (if I need to base it on the Bible), regardless, I should listen to the teaching of the Church as my guide, since that is what Jesus created here on earth.
I can’t argue with Jesus’s Church, I have to submit to Him. Therefore I confess my sins, to God, as a priest listens to me and guides me.
