Some Churches take communion very seriously, NOTE: Scripture above. Example: Our Pastor makes it very clear how Holy communion is and the implications of taking communion when we are out of sorts with God (regarding sin our hearts). I have even heard of some places not allowing visitors to partake communion because of this since they are uncertain of the visitors spiritual condition. The Church is accountable to God for it's people. Our Pastor will let anyone partake; but he ensures that all present at least acknowledge they understand the implications if they are 'unworthy'. It's not that Christ is not available to All who ask, it is a process to grow the Church in Holiness.... 'Go make things right between your brother (and God) before bringing your sacrifice to the altar' (Matt 5:23) Our altar sacrifice is Jesus Christ: Communion is our remembrance of that event and a time for cleansing our souls.
