How is John best described based on his community worship activities?

John can be best described as religious if his community worship activities indicate a structured practice of faith, such as attending services, participating in rituals, and being actively involved in a religious community. This would imply a commitment to specific beliefs and traditions that are inherent in organized religion.

Being classified as spiritual could suggest a broader and more personal approach to faith that is not tied to a formal religious structure. Spirituality often emphasizes individual connections with the divine or the universe, which may not necessarily involve community worship.

The terms agnostic and existentialist refer to particular philosophical stances rather than a dedication to worship activities. An agnostic person would generally maintain uncertainty about the existence of a deity and may not engage in community worship at all. An existentialist focuses on individual experience and meaning, often questioning traditional beliefs, which again does not align with the active participation suggested by community worship.

Therefore, the answer of John being religious reflects his engagement and involvement in organized community worship activities that denote adherence to particular faith practices and beliefs.
