Organised religion provides a structure to one's faith.
I like that you can go see someone who you know will (or should) be knowledgeable in this religion and able to help you learn and progress on your journey, to walk you through the faith and be there for you.
I appreciate formal rituals for their own sake, for their familiarity and comfort, for how they bring the community together all partaking in the same thing and imbuing it with spiritual meaning.
I like that there are places for people who feel called to serve God as a lifestyle, taking themselves out of the saecular world. Becoming clergy, monks, etc. These are available options in many faiths.
I like how organised religion is able to provide charity in large amounts.
I appreciate hierarchies and how it makes things feel more formalised. It makes those rituals seem somehow more real when done or presided over by someone or some folks who has/have trained to do this.
I love how organised religion can be there when you need it - a physical building, a service, a shared ritual, shared prayer, shared activities, etc. These things are so beneficial for the human psyche.
I think organised religion is much more good than bad.
