What the two traditions hold in common
- The historic creeds. Both confess the Trinity and the full deity and humanity of Christ in the words of the Apostles' and Nicene Creeds.
- Infant baptism. Both baptise babies, unlike Baptist and most free evangelical churches.
- A sacramental instinct. Baptism and the Eucharist are treated as genuine means of grace rather than bare symbols.
- The church year. Advent, Christmas, Lent, Holy Week, Easter and Pentecost shape worship in both traditions.
- Ordered ministry and liturgy. A Lutheran service and a Catholic Mass share the same ancient Western skeleton: confession, readings, sermon, creed, Eucharist.
Justification: the heart of the quarrel
The Reformation turned on how a person is put right with God. Luther taught that we are justified by grace alone, received through faith alone; good works are the fruit of salvation, never its cause. The Council of Trent replied that justification also involves real inner renewal and cooperation with grace, and it condemned the bare formula of faith alone.
In 1999 the Catholic Church and the Lutheran World Federation signed the Joint Declaration on the Doctrine of Justification, agreeing on a shared core: salvation is God's gift from first to last. It was a remarkable step after 480 years, though scholars on both sides admit that not every difference was dissolved.
Authority: Scripture, tradition and the Pope
Lutherans hold Scripture to be the final rule of faith, with creeds and confessions such as the Augsburg Confession serving as trusted but subordinate guides. Catholics receive Scripture and Tradition together, interpreted by the teaching office of bishops in communion with the Pope. Lutherans have no papacy at all; their churches are organised nationally under synods and bishops.
Sacraments in practice
Rome counts seven sacraments. Lutherans generally count two, baptism and the Lord's Supper, while retaining confession and absolution as a treasured practice. On the Eucharist both affirm that Christ is truly present, but they explain it differently: Catholic teaching speaks of transubstantiation, while Lutherans say Christ is given in, with and under the bread and wine and decline to define the mechanics. Catholic priests in the Latin rite are celibate men; Lutheran pastors may marry, and most Lutheran churches in Europe ordain women.
Mary and the saints
Luther himself spoke warmly of Mary, and Lutherans honour her and the saints as examples of faith. What they decline are the later defined dogmas, the Immaculate Conception and the Assumption, and the practice of asking the saints to intercede, since Christ alone is mediator in Lutheran teaching.
Both churches in Britain
The contrast in scale here is striking. The Catholic Church has millions of adherents across the UK, with its hierarchy in England and Wales restored in 1850 and parishes continually renewed by migration from Ireland, Poland and far beyond. Lutheranism, despite its size in Germany and Scandinavia, has always been a small presence in Britain: chaplaincies and congregations serving German, Nordic, Latvian, Polish and international communities, many linked through the Lutheran Council of Great Britain, alongside English-speaking congregations such as those of the Evangelical Lutheran Church of England.

Can a Lutheran receive Catholic communion?
Ordinarily no. Catholic discipline reserves communion for Catholics in good standing, because sharing the Eucharist is understood to express full church unity. Many Lutheran congregations, by contrast, welcome any baptised Christian to the table. If you are exploring either tradition, simply receive a blessing until you know where you stand; nobody will think it odd. For the wider Protestant picture, see our guide to Protestant denominations.
