Today at the Mass I attended (the 20th Sunday after Pentecost), I saw the phrase in its original context--St. Paul's epistle to the Ephesians, Chapter 5:
Brethren, see how you walk circumspectly, not as unwise, but as wise; redeeming
the time, because the days are evil.
What a great verse! What a great passage! I'm so embarrassed that I didn't pick it out until now. Seriously, I've read that letter a few times and heard it at Mass -- I dunno how many times. I'm sure that anyone reading this blog is unimpressed with the gaps in my scriptural and cultural knowledge. Remember, I'm a public school kid.
