Many times we get so caught up in the rules and rubrics it’s easy to lose sight of our true loving God. All the comments made here are very accurate and true - and in my mind, becoming the truest, strongest member of the Body of Christ is living to the teachings of Jesus Christ, Scripture, and the Magisterium of the Catholic Church.
However, I recognize that not everyone believes that, unfortunately. So I offer this – assuming that you are someone that truly loves Jesus Christ and wants a strong relationship with Him, realize that all of our concepts of family, love, and intimacy came for God! The human race learned it from Him. So many times, you can think about your own experiences and beliefs of love and family, and believe in your heart that God wants you to treat Him the same way.
So imagine a spouse, or family member, that continues to disappoint you (analogous to sin with God), who never “reconciles” (confesses) with you that they hurt you or your feelings, they are sorry, and they will try not to do it again. It’s like the bad movie where the husband keeps saying “Don’t worry honey, I love you”, yet goes on living a debauchery life.
Is that a good relationship/ Would you really believe that person loves you?
So we need to talk to our loved ones when we hurt them, to say we are sorry. How does the Bible say we should do that? Red Matthew 16:19 -" I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”
Since we cannot talk directly to God in the flesh, we confess to the Body of Christ - our priests. It is not up to you to rationalize the best way to do it, if you love God, you will do it the way He asks you to.
There are many benefits to Reconciliation as a sacrament , but I wanted to share with you that it’s likely your own beliefs about love and family should be applied to God as well if you love Him.
