Belief or Faith?

Editor’s Note: Reflection on the Mass readings for the Twenty-First Sunday in Ordinary Time (Year B) –  Joshua 24:1-2, 15-17, 18; Psalms 34:2-3, 16-17, 18-19, 20-; Ephesians 5:21-32; John 6:60-69. This series usually appears each Wednesday.

Belief in God is rather widespread, at least in America.  Various surveys show that over 90% of Americans “believe in God.”

But belief and faith are not quite the same thing. 

When many people say “I believe in God” they mean that they believe that God exists, that “there is a God” somewhere up there.  Nothing wrong with having such a conviction, of course.  But bear in mind that Satan has no doubts about the existence of God.  He just refuses to serve him.

True biblical faith involves must more than conviction.  It is not only “belief that” but “belief in.” When we have faith in a child or a lover who may have self-doubts, we look the person in the eye and say “I believe in you.”  More than just conviction, we have confidence in that person . . . that he or she won’t let us down.  Faith in someone means that we can entrust ourselves to that person, that we can take a risk, allow ourselves to be vulnerable because the person is trustworthy.

When a couple says “I do” at the altar, this is the faith they are publicly expressing in each other, a trust that leads to mutual commitment.  Because of this faith, they pledge to be faithful to each other, to be true, to be loyal, to entrust themselves to one another and serve one another for the rest of their days.

This is what Joshua asks of the Israelites in this Sunday’s first reading.  He didn’t ask them if they believed in the existence of the Lord, the God of Abraham, Isaac, and Jacob.  He asked them who would serve the Lord.  And the people responded that yes, they would serve him, based on the faithful way the Lord had provided for them.  He had proved to them that He was worthy of their trust by the way he had delivered them from evil and taken care of their every need.

This is echoed in Ephesians teaching on marriage.  Husbands and wives believe in each other enough to commit themselves, to give themselves to each other totally.  Part of what we human beings have to give to another is our future.  Total commitment therefore has to mean that we give ourselves forever, without reservation.

It’s one thing to say yes, I believe in you, I entrust myself to you, I commit myself to you. It’s quite another to live it day in and day out.  Certain moments come that put this commitment of faith to the test.  Lots of disciples followed Jesus and liked his healings and his profound words about God’s love and how the meek shall inherit the earth.  But when he started talking about eating his body and drinking his blood, it was just too much for many to bear.  Some complained and scoffed.  Many silently slipped away.  Many spouses slip away in similar fashion when the going gets tough.

To be truly faithful to another human being till “death do you part” is hard enough.  Thankfully God offers the spiritual power of grace through the sacrament of matrimony to all those courageous souls willing to rise to the challenge.  But to be truly faithful to a God whom you can’t see is humanly impossible.  It takes the supernatural gift of grace.  That’s what Jesus means in John 6:44 that “no one can come to me unless the Father draws him.”

So true biblical faith entails faithfulness or lifelong commitment, come what may.  It is a supernatural gift that only God can give.

But that’s not an excuse for doubt and unfaithfulness.  Faith is a gift, but is also a virtue, which is like a spiritual muscle.  It is given to each one who is born again through baptism, just like muscles are given to everyone born into this world.  Are your muscles weak?  Perhaps that’s because you haven’t exercised them?  Is your faith weak?  Perhaps it’s for the very same reason.

Dr. Marcellino D'Ambrosio

Dr. Marcellino D’Ambrosio writes from Texas. For his resources on parenting and family life or information on his pilgrimages to Rome and the Holy Land, visit or call 1.800.803.0118.

Raised in Italian/Irish neighborhood in Providence, RI, Marcellino D’Ambrosio never thought about being anything else but Catholic. But like other Catholic teens, his faith was the last place he looked for fulfillment. Following in the footsteps of his parents, both professional performers in their single years, Marcellino set his sights on stardom, playing bass guitar in several popular rock bands by the time he was 16. At that time he encountered a group of Catholics whose Christian life was an exciting adventure, an adventure worth living for. So he laid his bass guitar aside and embarked on a road that led to a Ph.D. in historical theology from the Catholic University of America. His doctoral dissertation, written under the direction of the renowned Jesuit theologian, Avery Cardinal Dulles, focused on one of the theological lights of the Second Vatican Council, Henri Cardinal de Lubac, and his recovery of biblical interpretation of the early Church fathers.

His writing has been published in the international journal Communio, Abingdon’s Dictionary of Biblical Interpretation, the Tablet, Catholic Digest, Our Sunday Visitor, and Catholic News Service’s syndicated column "Faith Alive." His popular book, Exploring the Catholic Church and video course by the same name (known as Touching Jesus through the Church in the USA) have been used in hundreds of parishes all throughout the English speaking world. The Guide to the Passion: 100 Questions about the Passion of the Christ, of which he is co-author and co-editor, may prove to be the fastest-selling Catholic book of all time with over a million copies sold in less than three months.

Dr. D’Ambrosio, the father of five and a business owner, brings to his teaching a practical, down-to-earth perspective that makes his words easy to understand and put into practice. Audio and video recordings of his popular teaching are internationally distributed. He often appears on the international Eternal Word Television Network is regularly heard on the nationally syndicated radio show "Catholic Answers Live." Dr. D'Ambrosio has been a guest on Geraldo Rivera, At Large on FoxNews Channel, the Bill O'Reilly radio show and Radio America's news program Dateline: Washington.

In 2001 Dr. D’Ambrosio left his position at the University of Dallas to develop the work of Crossroads Productions, the apostolate of Catholic renewal and evangelization that he co-founded twenty years ago, and to more directly oversee the growth of Wellness Opportunities Group a company dedicated to helping people improve the quality of their lives physically, mentally, and financially. He, his wife Susan, and their five children, reside just outside of San Antonio, TX.
