In my sermon this past week I argued that John’s leaping in the womb (Luke 1) is a sure sign that God does not need a certain IQ before He can grant faith. He works even in the unborn (brethos). This also proves that God recognizes those in utero as persons. So yes, baptized infants do have faith; a faith given from above. Leithart observes in his book Baptized Body that infants learn to respond to their mother’s voice even before birth. They are able to quickly distinguish between strangers and members of the family. Leithart asks: “If infants trust and distrust human persons, why can’t they trust in God?” Behind certain assumptions about infant faith is the idea that infants must express their faith through certain theological truths, implying that only those of a certain age of maturity can do this, but the Scriptures never require that all faith is expressed in the same manner. The faith of a down syndrome child is differently expressed than the faith of a healthy adult. Leithart also adds that another assumption is that God is less available to an infant than to other humans. But God’s work of grace is not dependent on intellect or certain verbal abilities. Covenant infants mature in their faith just as new adult converts mature in their new faith.
