How do we know the significance of taking communion?

Taking communion is significant as it represents our mystical union with Christ, affirming that we participate in His death, which brings us salvation. The practice is not a mere tradition; it is a command from Christ Himself, as seen when He instructs His disciples to 'Take, eat' (Mark 14:22). This act symbolizes a deeper relationship, akin to a marital bond, highlighting that believers are chosen and called to partake in this sacred meal. The bread and wine are not a means of grace in themselves but are reminders of the grace already given through Christ's sacrifice.
