I had a relationship with God, and that was enough. I didn't see any value in joining an organization that would just get in the way.
Because of a relationship with a Catholic friend, I started attending a Catholic Mass. The formal liturgy was similar to the Church services of my childhood, and I appreciated the depth of what was happening during the celebration. For a while, I attended Mass without being a full member of the Church. For the first time in years, I experienced spiritual growth within a Church community and grew beyond the self-centered spiritual box I had put myself in.
