As a Catholic nerd, I had to check. Yes. :)
echo -n 'Hail Mary full of grace, the Lord is with thee. Blessed are thou amongst women and blessed is the fruit of thy womb, Jesus. Holy Mary, mother of God, pray for us sinners, now and at the hour of our death. Amen.' \

210Depending on the translation(i.e. trespass is too long), the Lord's Prayer either fits or is a few characters too long.
Does the regular prayer refer to the "hour of our death"? Or is this only for last rites?
Does "Hail Mary ..." fit in 280 characters?
