Christian Relationships, Families and Marriage

Christian relationships: shared beliefs, different interpretations

Christians generally understand relationships as involving love, care and responsibility towards other people. However, shared faith does not mean that every Christian agrees about how a household should be organised or whether an unmarried couple should live together. Differences often arise from how Christians interpret biblical teachings and apply them to twenty-first-century life.

A useful distinction is between the ideal a Church teaches and the choices made by individual Christians. For example, a Church may teach that marriage is the proper setting for a sexual relationship, while some of its members choose to cohabit.

Marriage as a sacred, lifelong relationship

Christian Churches describe marriage as a ‘gift of God in creation’. This means that marriage is more than a legal contract: it is understood as part of God's purpose for human relationships. It is a sacred bond involving a lifelong commitment to another person.

In Mark 10:6–8, Jesus refers back to the creation account in Genesis. He says that God made human beings ‘male and female’, and that a man will leave his parents and be united with his wife:

‘The two will become one flesh.’

‘One flesh’ expresses a deep union, not simply two people sharing a home. Marriage joins their lives together and establishes a new relationship with responsibilities towards one another. Leaving one's parents indicates that the marriage becomes a central human relationship.

Christian teaching also compares marriage with the relationship between Christ and the Church. The couple's shared life is therefore understood as reflecting a faithful and enduring relationship, rather than an arrangement based only on convenience.

Families, children and the wider community

Traditionally, Christians regard marriage as the basis of family life and the best setting in which children should be born and brought up. Its intended permanence provides a stable framework for care and shared responsibility. Family life is not only about having children: it also involves the way people support one another and respond to difficulties.

The Faith and Order Commission, which advises the Church of England's General Synod, explains that marriage ‘strengthens community’. A couple can learn habits within their marriage that also help them become good friends and neighbours. This connects a private relationship with the wellbeing of wider society.

Its report Men and Women in Marriage also describes how children can learn from seeing a couple cope with ‘disagreements and disappointments’. The point is not that married couples never disagree. Rather, working through difficulties can demonstrate the strength of a shared life and the responsibilities involved in commitment.

What a Christian wedding expresses

A wedding is a rite of passage: a ceremony marking an important change in people's lives. A Christian wedding recognises and celebrates the beginning of marriage as a sacred, lifelong relationship. Its words and actions express what the couple is committing to, rather than simply celebrating their feelings on that day.

The Church in Wales marriage service provides an example of a Christian ceremony in Britain. The minister welcomes the congregation and explains Christian beliefs about marriage. The congregation and couple are asked whether there is any reason why the marriage cannot lawfully take place. Bible readings, and sometimes a short sermon, connect the couple's marriage with Christian teaching.

The couple then make declarations promising to live according to God's will, to love, honour and care for each other ‘in sickness and in health’, and to remain faithful as long as they both live. These promises express mutual responsibility and sexual faithfulness.

With their hands joined, they make their vows — solemn promises to take one another in marriage:

‘For better for worse, / For richer for poorer, / In sickness and in health, / To love and to cherish, / As long as we both shall live.’

These words show that commitment is intended to last through changing circumstances. ‘For richer for poorer’ makes financial success no condition of love; ‘in sickness and in health’ promises care when a partner needs support. ‘As long as we both shall live’ expresses the lifelong nature of marriage. The vows also refer to ‘the will and purpose of God’, placing the relationship within the couple's faith.

The couple exchange a ring or rings with the words:

‘Receive this ring in token of my love and faithfulness. I honour you with my body, and all my possessions I share with you.’

The ring is therefore a visible token of love and faithfulness. The accompanying words connect it with bodily fidelity and sharing material possessions: marriage involves a shared life, not just a romantic attachment.

The minister declares the couple married and pronounces a blessing as they kneel. Prayers for their future life together express their desire for God's help and care in living out their promises. During the service, the couple and two witnesses sign the marriage schedule or document, which the minister sends to the local register office. This records the marriage's legal recognition alongside its religious meaning.

The wedding marks the beginning of the marriage; the continuing relationship is where the couple lives out these responsibilities.

Women and men: equality and family responsibilities

Christianity teaches that all people are God's creations and have equal worth. Galatians 3:28 states:

‘There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.’

Christians differ over what this equality means for everyday roles. Some traditional Christians believe that women and men are equal in worth but have different responsibilities. They draw on the creation account, in which Adam is created before Eve, and on Paul's statement that ‘the head of the woman is man’ in 1 Corinthians 11:3. These interpretations can support male leadership in the household, with women taking primary responsibility for housekeeping and childcare.

More liberal Christians argue that biblical passages reflecting male authority need to be understood in the context of the societies in which they were written. They emphasise equality in Christ and Jesus' respectful treatment of women. They therefore support equal opportunities for women and men in family life and employment, with responsibilities shared rather than fixed by gender.

These interpretations have practical consequences. A traditional household might assign different duties to each partner; an egalitarian household might divide paid work and childcare according to circumstances and abilities. In Britain, shared parental leave became available in 2015, allowing eligible parents to share time away from work to care for a baby rather than assuming that this must always be the mother's responsibility.

Marriage outside a religious tradition

In a pluralist society, Christians may form relationships with people from another Christian denomination, a different religion or no religion. Inter-faith marriage specifically means marriage between people of different faiths; marrying a Christian from another denomination is a different situation.

Such relationships can raise questions about both the wedding and everyday family life. Partners may need to agree which festivals to celebrate, how to follow religious dietary rules, and which religion their children will be brought up in. Different expectations about gender roles, contraception, death and the afterlife may also require discussion. Family or religious-community opposition can create additional pressure.

Christian traditions place different conditions on religious weddings. In the Orthodox tradition, an Orthodox Christian can marry in church only if the other partner is a baptised Christian. A relationship with someone of another religion therefore does not automatically qualify for an Orthodox church wedding.

In the Catholic tradition, a marriage between a Catholic and a baptised non-Catholic Christian needs express permission from the appropriate Church authority. Marriage to an unbaptised person, such as someone of another religion or none, needs a dispensation — an exemption from a Church-law restriction — for the marriage to be valid. Both partners must understand and accept the essential purposes and properties of marriage.

Under Canon 1125, the Catholic partner promises to protect their own faith and do all in their power to have all children of the marriage baptised and brought up Catholic. The non-Catholic partner must be informed of this promise and its obligations, but is not required to make or agree to the same promise. The Bishops' Conference of England and Wales explains that the Catholic undertaking is to do ‘all that I can within the unity of our partnership’. It advises couples to discuss and agree about children's baptism and education before the wedding, without demanding an undertaking from the non-Catholic partner that Church law does not require. These responsibilities show how marriage outside one's tradition affects continuing family life, not just the ceremony.

Cohabitation: why Christians disagree

Cohabitation means living together as a couple in a sexual relationship without marriage or a civil partnership. Some couples cohabit before marrying; others do not intend to marry.

The Catholic Church, Orthodox Churches and more conservative Anglicans oppose sexual relationships outside marriage. They regard sex as sacred and believe that its proper setting is the lifelong commitment of marriage. From this perspective, physical union should express a complete commitment of lives: sexual intimacy without marriage separates the two. Some Baptist churches may refuse to marry a couple who are cohabiting.

Some liberal Anglicans accept cohabitation within a loving, faithful and committed relationship, while still regarding marriage as the ideal. They place greater emphasis on the quality of the relationship than on whether the couple has already married.

The disagreement is therefore not simply about whether love matters. Both approaches value commitment, but they differ over whether marriage is necessary for a sexual relationship to be morally acceptable. A reasoned judgement should consider whether loving behaviour alone adequately expresses commitment, or whether marriage's explicit lifelong obligation adds something essential.
