As the UK leaves the EU, clergy have been offering their suggestions on how to pray.
Discussion on trade, immigration and technology will continue for months between UK and EU politicians.
Here are just a few ways that Christian leaders have suggested praying:
Revd Barbara Glasson, President of the Methodist Conference:
"However we feel about today
We mark this Brexit day
As people who grieve or celebrate together
Loved equally, freely and unconditionally
By the one wise all-seeing God
Either way let us hold this day gently
Giving ourselves permission to leave
Without elation or despair
Determined to love our neighbour
Support the weak and welcome the stranger
Lord of all life
Let your servants depart in peace
And live according to your Holy Law"
The head of the Church of England has offered his contribution:
Cardinal Vincent Nicholls, the Archbishop of Westminster in the Catholic Church said: "As the UK formally leaves the European Union, we have an opportunity to move beyond the divisions which have been evident at many levels in our society.
"It is important for everyone to renew a commitment to each other through everyday acts of kindness, being good neighbours, welcoming the stranger and caring for the most vulnerable in our society. In these ways we contribute to the common good at every level of society, from national politics to individual generosity, particularly for those in greatest hardship and uncertainty. As Catholics, with all people of good will, we commit ourselves to playing our role in this endeavour."
The Archdeacon of West Cumbria, Richard Pratt, prayed on Premier's News Hour.
