A “global wave of prayer” will propagate across the world from 10 to 20 May 2018: for 11 days between Ascension Day and Pentecost, prayers will be said for more people “to come to know Jesus”. “Thy Kingdom Come” is an event launched in 2016 by Archbishop Justin Welby, Primate of the Anglican Church, which is now in its third edition and has grown into an ecumenical call to prayer. Individuals, families and Church communities are all invited to join in. A website (www.thykingdomcome.global) provides resources and ideas for prayer, and proposals are also shared on social media with an increasing number of people pledging to pray. Thanks to cooperation with the Catholic Church in England, a “guide to praying with Our Lady” called “Journey with Mary” was issued this year alongside three booklets containing the texts of the traditional Catholic prayer of the “Liturgy of the Hours” to be used during the 11-day event. The website of the event also provides a series of videos in which Archbishop Welby gives insights into the meaning of prayer, particularly the invocation “Thy Kingdom Come”, in dialogue with representatives of other Churches, such as Cardinal Vincent Nichols; Pastor Agu Irukwu, president of Churches Together in England; and Gareth Powell from the Methodist Church. An interactive map on the website shows lights where people have pledged to pray around the world.
