I sometimes wonder whether we have made Christian holiness easier to recognise from the outside than to understand from the inside. We may recognise the things a Christian refuses to do, the company a Christian avoids, or the customs a Christian observes. But how do we recognise a heart that has been made holy? Does holiness mean separation from the world, or does it also mean learning to love the people in it?
I understand why Christians have emphasised separation. Scripture does not tell us to embrace every desire or value around us. In 1 John 2:15–17, believers are warned against loving the world and its desires. Paul similarly urges Christians in Romans 12:1–2 not to conform to the pattern of this age but to be transformed through the renewing of their minds. These are serious warnings. Love cannot become an excuse for greed, pride, immorality, or indifference to God’s will.
Yet I think we need to ask what these passages mean by the world. John tells us that God loved the world and sent his Son so that the world might be saved (John 3:16–17). The same New Testament that warns against the world’s desires presents humanity as the object of God’s redemptive love. These passages are not contradictory. They challenge us to distinguish between people whom God loves and the desires and loyalties that turn human life away from God. If we confuse the two, we risk resisting the very people we are called to love.
Jesus’ prayer in John 17:14–18 makes this distinction especially important to me. He acknowledges that his disciples do not belong to the world in the same way that the world belongs to its prevailing order. He asks the Father to protect them from evil, but he does not ask that they be taken out of the world. Instead, he speaks of sending them into it. Sanctification and mission appear together. The disciples are to be different, but their difference does not make their presence unnecessary.
I find a similar connection in Romans 12. After calling believers to resist conformity, Paul describes sincere love, hospitality, patience, care for enemies, and overcoming evil with good. The chapter does not allow nonconformity to remain merely a list of things avoided. It asks what transformed people will do. Jesus’ teaching about salt and light in Matthew 5:13–16 makes the same point from another direction: the disciples’ distinctiveness should become visible in good works that direct attention to the Father.
James 1:27 brings the question even closer to home. He describes pure religion through care for orphans and widows in their distress, alongside keeping oneself unstained by the world. Both belong in the same verse. I find it difficult to defend a version of holiness that speaks confidently about personal purity while remaining indifferent to people who are suffering. If our separation leaves us less willing to serve, listen, show mercy, or carry another person’s burden, I think we need to examine what our boundaries are accomplishing.
This concern also belongs within my Wesleyan-Holiness understanding of the Christian life. In A Plain Account of Christian Perfection, John Wesley describes Christian perfection in terms of love for God and neighbour governing a person’s tempers, words, and actions. His understanding was not that a sanctified person had no further need to grow. He recognised both a decisive work of sanctification and continuing growth. Holiness, then, cannot simply mean acquiring a recognisable religious appearance. It concerns what grace is doing in the heart and how that work becomes visible in life.
The official description of Nazarene belief also connects holiness with Christlikeness, discipleship, evangelism, and compassion. That matters to me because it places compassionate engagement within the denomination’s public understanding of its mission. The denomination’s Historical Statement records a tradition of practical service, including relief efforts and medical ministries. These examples do not prove that every Nazarene congregation has always lived out this calling consistently, but they remind us that our heritage includes more than warnings against sin.
Someone may reasonably object that greater engagement with society can weaken Christian conviction. That danger is real. A desire to be accepted can lead Christians to excuse what they once recognised as wrong. But withdrawal has its own danger: we may preserve our distance while neglecting our responsibility to our neighbours. Neither uncritical accommodation nor indiscriminate avoidance is an adequate measure of faithfulness. Even Paul, in 1 Corinthians 5:9–13, clarifies that avoiding immoral people altogether would require leaving the world. He maintains moral accountability within the church without treating complete social withdrawal as the Christian calling.
I have therefore come to see the question differently. Christian holiness does require separation from sin, but separation is not the whole purpose of holiness. We are set apart for God, and that consecration should shape how we treat the people around us. We can refuse what destroys life without despising those who need grace. We can maintain convictions without making distance from others our evidence of superiority. We can love without pretending that every desire or action is good.
For me, the better question is not simply, ‘What have I separated myself from?’ It is also, ‘What kind of person is God’s grace making me, and what good does that holiness bring to my neighbours?’ If we are becoming more like Christ, our holiness should be visible not only in what we refuse, but also in the truth we uphold, the mercy we show, and the people we are willing to serve.
