How often is it talking about saints that are in Heaven? How often does it say that there is a checklist needing to be approved by the rcc, or any other official body, in order for someone to be considered a saint?
All in Christ are saints, yes...but the practice of 'declaring' saints is mostly so that the Church would have Christians to look up to as good examples of our faith..I think.. they are people who have lived holy lives and glorified God.
