Brother, it is collectivist.
You may have a personal relationship with your man in the sky and negotiate your own entry into Utopia (paradise) after death, but who will teach you the tricks of such an entry to be sure? Faith is not knowledge you can be sure about. You cannot use your own mind. To raise your expectations to achieve Utopia (paradise in the sky), you must turn to a collective dogma about trinity, grace and other things. Many first Christians were woshiping a single god for about 200 years until organized church enforced Trinity.
