Confirmation Candidates Ask About the Trinity
A parish confirmation programme has 16 candidates aged 13 to 14. In the second of two 45-minute sessions before the bishop's visit, one candidate reports that her Jehovah's Witness grandmother calls the Trinity a pagan invention. Another says, 'Jesus prayed to the Father, so there must be two Gods.' A third asks why God would need three persons at all. Parents will attend the second session, and the catechist knows that one parent is suspicious of 'too much doctrine' while another wants the Nicene Creed taught word for word. The catechist must explain the Trinity without falling into modalism or tritheism, answer the prayer objection, and leave candidates able to give a reasoned answer in their own words. The parish priest has asked for a plan that is faithful to Catholic teaching and intelligible to 13-year-olds.
1. How should the catechist explain the Trinity to 13-year-olds without modalism or tritheism? Include the grammar of 'one substance, three persons'.

The catechist should begin with the Christian claim that there is one God, not three. 'Person' in Trinitarian language does not mean a separate human individual; it means a distinct relation within the one divine life. The Father is unbegotten, the Son is begotten of the Father, and the Spirit proceeds; these are relations, not ranks, modes or separate beings. The Nicene Creed gives the grammar, while Scripture gives the raw material: John 1:1-18, John 14:16-17, John 20:28, 1 Corinthians 12:3 and 2 Corinthians 13:14. The catechist should name the errors: modalism is one God wearing three masks; tritheism is three gods in a team. Analogies such as water, ice and steam, or the sun and its rays, are limited and can mislead; they may be used only with a warning. The doctrine is not an extra puzzle but the Christian way of saying that the God who creates is the God who saves in Christ and is present in the Spirit.
2. How should the catechist answer the objection 'Jesus prayed to the Father, so there must be two Gods'?

The answer should be that Jesus prays to the Father because he is the incarnate Son, truly human, and prayer is the human response to God; the eternal Son does not cease to be God. The Church's Chalcedonian teaching says one person, two natures, divine and human, without confusion or separation. So the praying Jesus is not a second God; he is the one Son addressing the Father in his humanity and in the communion of the Trinity. The Spirit also intercedes, as Romans 8 says. The candidate's inference assumes that prayer must be between two separate beings; in the Trinity the persons are distinct but not separate. The catechist should avoid saying 'Jesus is the human side of God', which sounds like modalism or a split personality. A good image is a conversation within one life, but even that must be corrected by the Creed.
3. Plan the two sessions and the parents' involvement so that the doctrine is taught faithfully and intelligibly.

Session one should start with the candidates' questions, then read John 14 and the Nicene Creed. The catechist should teach the grammar with a simple diagram of relations, not a triangle of three gods, and name modalism and tritheism. Session two, with parents present, should include a short presentation, common misreadings, and a question-and-answer time. A handout could contain the Creed, key Scripture references and a warning about inadequate analogies. The catechist should treat the Jehovah's Witness grandmother's objection fairly, not caricature it, and invite candidates to explain the doctrine in their own words. Assessment could be a short written paragraph. The reasoning is that 13-year-olds need concrete language and repetition, parents need transparency, and doctrine should be connected to prayer and worship rather than presented as an abstract puzzle.
