Saint... Spiritually pure morally blameless. Most holy ONE...
To be spiritually pure is already without sin. morally blameless, means a perfect moral standard.. God's standard... So the word Saint...Hagios in greek, means it is already a person that STOPPED SINNING! So if you ask a saint ... Do you still sin he has to lie to say Yes, And if He says NO you guys will crucify him calling him a lier, so what chance does a sinless person have here with you? NONE... but then what does it matter, we are just glad you are not the judges, becasue your judgement is not His!
Now a Saint is already a sinless man, and how can a sinner teach a sinless man to be perfect? That means these people appointed by God is perfect!...
