God is revealed as perfect
interior holiness.
Isaiah 6:3
"Holy, holy, holy is the Lord of hosts!" they
(the
Seraphim) cried one to the other.
We are called to that same
holiness.
Leviticus 19:2
"Speak to the whole Israelite community and tell
them:
Be holy, for I, the Lord your God, am holy."
1 Peter 1:15-16
As he who called you is holy, be holy yourselves in
every aspect
of your conduct, for it is written,
"Be holy because I (am) holy."
