What this dot point is asking
Eduqas wants you to explain what Christians believe about the nature of God (one God who is omnipotent, loving and just) and the distinctively Christian doctrine of the Trinity (one God in three persons). This is the opening topic of the Component 2 Study of Christianity, and it feeds straight into the 15-mark evaluation question on whether the Trinity is consistent with belief in one God. You need both the content (the qualities and the three persons) and the sources of wisdom and authority that Eduqas rewards in the c and d questions.
The qualities of God
Christianity is monotheistic: there is only one God, the eternal creator of everything. Christians describe this God using attributes that run through the Bible and the historic creeds.
These attributes are grounded in sources of wisdom and authority, not invented by philosophers. "God is love" (1 John 4:8) supports benevolence; "with God all things are possible" (Matthew 19:26) supports omnipotence; and the Psalmist's "he will judge the world in righteousness" (Psalm 9:8) supports justice. Christians hold these together: God's power is always exercised lovingly, and his justice is the justice of a loving father, not arbitrary cruelty.
The problem these qualities raise
Holding omnipotence and benevolence together creates the classic challenge known as the problem of evil: if God is all-powerful he could stop suffering, and if he is all-loving he would want to, yet suffering exists. Eduqas examines this directly in Component 1 and in Christian beliefs, so you should be ready to note here that the qualities of God are not just descriptive but generate the hardest question believers face. Christians respond in several ways, including free will and the idea that God brings good out of suffering, which the dedicated dot point develops.
The oneness of God
The oneness of God matters because it links Christianity to its Jewish roots and distinguishes the Trinity from belief in many gods. The Shema, "Hear, O Israel: the Lord our God, the Lord is one" (Deuteronomy 6:4), is shared with Judaism, and the first commandment forbids other gods. So when Christians explain the Trinity, they are not abandoning monotheism: they insist there is one God, and the three persons are how that one God is revealed and experienced.
The doctrine of the Trinity
The doctrine is biblical, even though the word "Trinity" is not in the Bible. At the baptism of Jesus (Matthew 3:16 to 17) the three persons appear together: the Son is baptised, the Spirit descends like a dove, and the Father's voice declares "This is my Son". Jesus commands his followers to baptise "in the name of the Father and of the Son and of the Holy Spirit" (Matthew 28:19), and Saint Paul blesses a church with "the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit" (2 Corinthians 13:14). The doctrine was defined against early disputes in the Nicene Creed (from 325 CE), which Christians still recite, affirming the Son is "of one Being with the Father".
Common and divergent views
Almost all Christians (common view) accept the Trinity as defined at Nicaea, and it is recited in the creeds across Catholic, Orthodox and most Protestant churches. There is divergence in emphasis and explanation: the Eastern Orthodox tradition disputes the Western addition of "and the Son" (the filioque) to the creed; some smaller groups historically rejected the Trinity altogether. For the exam, treat the Trinity as the mainstream Christian belief while noting that it is a mystery Christians explain in different ways, never claiming to fully comprehend it.
Why the Trinity matters for Christians
The Trinity is not abstract theory: it shapes worship and life. Prayer is often addressed to the Father, through the Son, in the Holy Spirit. Baptism is performed in the threefold name. And the Trinity expresses that God is, in his own being, relationship and love, which underpins the Christian command to love. For the exam, the Trinity also links forward: the Son connects to the incarnation and salvation, and the Holy Spirit connects to the church and the sacraments.

Exam-style practice questions
Practice questions written in the style of WJEC Eduqas exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Eduqas C120 2019 (style)2 marks[a] What is meant by omnipotent?Show worked answer →
This is the 2-mark (a) AO1 definition question. Give a precise, accurate definition of the key term: omnipotent means all-powerful. Develop it slightly to secure both marks, for example "all-powerful: Christians believe God has unlimited power and created and sustains the universe". A bare one-word answer risks only 1 mark, so add a short clause that shows understanding. Use the exact specialist term rather than a vague paraphrase.
Eduqas C120 2021 (style)8 marks[c] Explain Christian beliefs about the Trinity. Refer to sources of wisdom and authority in your answer.Show worked answer →
This is the 8-mark (c) extended AO1 question, and the instruction to refer to sources of wisdom and authority is compulsory for the top band. Make developed points and anchor each in a named source. Explain that Christians believe in one God in three persons: the Father (creator and sustainer), the Son (Jesus, God incarnate) and the Holy Spirit (God present and active in the world). Stress that these are not three Gods but one God, three in one. Support with sources: the baptism of Jesus in Matthew 3, where the Father speaks, the Son is baptised and the Spirit descends as a dove; the command to baptise in the name of the Father, Son and Holy Spirit (Matthew 28:19); and the Nicene Creed. The top band rewards thorough, accurate, developed knowledge with sources used correctly.
Eduqas C120 2022 (style)15 marks[d] "You cannot believe in one God and in the Trinity at the same time." Evaluate this statement. In your answer you should refer to religious beliefs and teachings, give reasoned arguments to support this statement, give reasoned arguments to support a different point of view, and reach a justified conclusion.Show worked answer →
This is the 15-mark (d) AO2 evaluation question, where the SPaG marks for the paper are awarded, so write in accurate continuous prose with correct specialist terms. Argue both sides and reach a justified conclusion. Arguments to support the statement: three persons appear to mean three beings, so monotheism and Trinity look contradictory; the strict monotheism of Judaism and Islam, which share the Shema ("the Lord is one"), sees the Trinity as compromising the oneness of God. Arguments for a different view: Christians hold the Trinity is one God in three persons, not three Gods, and the Nicene Creed and the Bible (the baptism of Jesus, Matthew 28:19) teach both oneness and threeness together; the doctrine is a mystery that expresses how the one God is experienced. Use specialist terms (Trinity, monotheism, incarnation, Nicene Creed) for the SPaG marks. A justified conclusion weighs whether the doctrine truly contradicts oneness or expresses it, rather than just asserting one view.
