According to the first commandment, what is forbidden?

The first commandment emphasizes the need to worship and honor the one true God, forbidding the worship of any other gods. This means that any denial of the true God, whether through outright atheism or the practice of idolatry, contradicts the essence of the commandment. The focus is on maintaining a proper relationship with God, recognizing His sovereignty and uniqueness.

Other options do not fall under the prohibitions outlined by the first commandment. Helping those in need is seen as a virtue within Christian teaching; seeking knowledge of the unknown can be interpreted in many ways, often positively; and participating in community rituals would depend on the context and nature of those rituals, which might not inherently conflict with the commandment. Hence, denial of the true God is the most direct and specific infraction related to the first commandment.
