Repent therefore -- that your sins may be forgiven.

At National Review Online, Kathryn Jean Lopez writes about the controversy regarding the
the St Patrick's Day Parade, in 2015.

All are welcome. The life of Christ demonstrates this — and then some. Cardinal Dolan has said this. Pope Francis said it in his Tuesday-morning homily in Rome. Across the street from Penn Station in midtown Manhattan stands St. Francis of Assisi Church, where there is a sign outside that says the same. St. Francis’s has Eucharistic Adoration from 8:30 a.m. to 5:00 p.m. every weekday, and there is Confession there too, for many hours throughout the day. Be reconciled to Christ. That is the invitation. Fallen away, lost, miserable, confused, trying. Come to the healing waters of eternal life.

Yes, we are all sinners in desperate need of God's Mercy.  We must all repent of the evil we participate in.

St Peter, in the Acts of the Apostles, says to the Jewish people in Solomon's Portico: Repent therefore, that your sins may be forgiven. (Acts 3:19).

That saying is no less pertinent today than it was in 33 AD.
