Today's verse from Matthew 5:48 reads "Be perfect, just as your heavenly Father is perfect." When we read that scripture in its proper context, however, we find where it flows from; a more wholistic and holy place - the love of others.
So perfection in God's eyes means loving perfectly, totally; not being totally distanced from others in the attempt to be pure.
Blessed John Paul II put it this way. “The perfection of the Christian life is measured, rather, by... love.”
This means that “perfection is possible and accessible to every human being, whether in a ‘religious institute’ or in the ‘world.’” In fact, a person who does not live in “the state of perfection” can nonetheless “reach a higher degree of perfection... than a person who lives in the ‘state of perfection’ with a lesser degree of love” (TOB 78:3).
And perfect love, St. John tells us, casts out all fear. What a sweet and liberating thought. What a freedom awaits the person who embraces the authentic Christian life!
