This weekend churches and christians from across the UK and Ireland are encouraged to come together in an act of witness to pray for the people of Ukraine and for an end to the conflict.
Tomorrow at 2pm Church Leaders will lead a large crowd in an act of witness outside the Ukrainian embassy in London.
The act of witness will include speeches from the church leaders such as Chair of Christian Aid and former Archbishop of York, John Sentamu.
Christian Aid-Chief Executive Patrick Watt spoke to Premier and said what you can expect to see this weekend: "On Saturday evening, we'll be projecting a message, we pray for Ukraine, on the side of Westminster Abbey, on the on the front of Methodist Central Hall in Westminster.
"Then on the Sunday, we'll be encouraging Christians up and down the country to come together in prayer at 2pm, for peace in Ukraine, and to pray together.
"A prayer has also been put together in partnership with the Russian Orthodox Church here in Britain.
"With their father, Stephen Platt, from the Russian Orthodox Church in Oxford, who's been very supportive of the call for peace in Ukraine.
"We're delighted to have the backing of church leaders from across the different churches and we think this will be a really powerful moment to unify for peace, up and down this country."
The Archbishop of Canterbury as well as the Archbishop of York has also set aside this Sunday as a day of prayer.
On Thursday, both Archbishops issued a pastoral letter to the clergy and people of the Church of England, calling on them to pray for peace in Ukraine.
They wrote: "This attack is an act of evil, imperilling as it does the relative peace and security that Europe has enjoyed for so long.
"The attack by one nation on a free, democratic country has rightly provoked outrage, sanctions, and condemnation.
"We lament with the people of Ukraine, and we pray for the innocent, the frightened and those who have lost loved ones, homes, and family.
"We continue to call for a ceasefire and the withdrawal of Russian forces as well as wide-ranging efforts to ensure peace, stability and security."
The Church of England is also supporting a call from Pope Francis for a Global Day of Prayer and fasting next week on Ash Wednesday.
