What Is Catholic Apologetics?

What apologetics is

As a lawyer defends a client, apologetics builds the rational case for the faith, for Catholicism as the fullness of Christian truth in the one Church Christ founded (see CCC 846-848). An apologist answers objections and clears up misunderstandings, aiming not to win but to lead others to Christ by speaking the truth in love (Ephesians 4:15).

Three branches

• Natural apologetics argues from philosophy and nature that belief in God is rational (see CCC 156).
• Christian apologetics defends Christ's basic teaching, that the Father sent Jesus to redeem us (John 3:16-17; 1 Corinthians 15:20-22), from Scripture, Tradition and history (see CCC 74-100).
• Catholic apologetics defends distinctively Catholic doctrines: the Church led by the apostles' successors and the pope (see Matthew 16:18-19; CCC 891-892), the sacraments, especially the Eucharist, and the intercession of Mary and the saints (see Revelation 12:17; 5:8).

Why it matters

Jesus is the truth (John 14:6), and God wills all to come to knowledge of the truth (1 Timothy 2:4), which sets us free (John 8:31-32). Apologetics plants seeds, persisting in love, knowing the Spirit changes hearts and that our true enemies are the devil and his demons (Ephesians 6:12).

How to begin

• Read the Gospels. St. Jerome said a Catholic not immersed in the Gospels does not know Christ. Read one a night, about thirty pages, then reread them. Then read Acts, Romans, 1 Corinthians, Ephesians and the other epistles, leaving Revelation for last.
• Read a catechism, ideally the Catechism of the Catholic Church (1992). Scripture must not be privately interpreted (2 Peter 1:20-21) but read with the Church, the pillar and foundation of truth (1 Timothy 3:15); the ignorant and unstable twist the Scriptures (2 Peter 3:16).
• Learn the objections from anti-Catholic literature, and the answers, from works like Karl Keating's Catholicism and Fundamentalism, Frank Sheed and Fr. William Most.
• Practice, and admit when you need to get back to someone.
• Pray for the Spirit's guidance; God speaks in the quiet of the heart (1 Kings 19:11-13).
• Use Scripture and Tradition, the deposit of faith (CCC 85-87), interpreted by the Magisterium (John 16:13; see Luke 10:16).
• Be patient; God works in his time (Romans 8:28; Matthew 6:33).

Apologetics is part of evangelization, bringing Christ's light to the world (John 8:12), and it is for every Catholic.

"Divisive"?

Some say disagreeing about religion is divisive. C. S. Lewis compared "mere Christianity" to a hallway: we must enter a room. Not all religions are roads up the same mountain; Christianity is the road God paved down to us, and Christianity and Buddhism could hardly differ more. True ecumenism understands others' beliefs as they are and cooperates on common ground. Ignoring differences breeds paralysis; honest, good-natured discussion of them leads to fewer divisions.

Prayer of St. Thomas Aquinas for apologists: Ineffable Creator, who from the treasures of your wisdom, have established three hierarchies of angels, have arrayed them in marvelous order above the fiery heavens, and have marshaled the regions of the universe with such artful skill, you are proclaimed the True Font of Light and Wisdom, and the primal origin raised high beyond all things. Pour forth a ray of your brightness into the darkened places of my mind; disperse from my soul the twofold darkness into which I was born: sin and ignorance. You make eloquent the tongues of infants. Refine my speech, and pour forth upon my lips the goodness of your blessings. Grant to me keenness of mind, capacity to remember, skill in learning, subtlety to interpret, and eloquence in speech. May you guide the beginning of my work, direct its progress, and bring it to completion. You who are True God and True Man, who live and reign world without end. Amen.
