No dedicated servant of Jehovah and faithful follower of his Son would want to show disrespect for Jesus ’ sacrifice by partaking of the Memorial emblems if he or she actually lacks clear evidence of being an anointed Christian.
وَبَيْنَمَا يَسْتَعِدُّ كُلٌّ مِنَّا لِلذِّكْرَى ،‏ يَحْسُنُ بِنَا أَنْ نُصَلِّيَ وَنَتَأَمَّلَ فِي ٱلرَّجَاءِ ٱلَّذِي وَهَبَنَا إِيَّاهُ ٱللهُ سَوَاءٌ كَانَ أَرْضِيًّا أَمْ سَمَاوِيًّا .‏
