free from spot
An echo of a common biblical phrase, as in 1 Peter 16-20:
"Because it is written, Be ye holy; for I am holy. And if ye call
on the Father, who without respect of persons judgeth according
to every man's work, pass the time of your sojourning here in
fear: Forasmuch as ye know that ye were not redeemed with
corruptible things, as silver and gold, from your vain
conversation received by tradition from your fathers; But with
the precious blood of Christ, as of a lamb without blemish and
without spot: Who verily was foreordained before the foundation
of the world, but was manifest in these last times for you, Who
by him do believe in God, that raised him up from the dead, and
gave him glory; that your faith and hope might be in God."
