The organisation claims the game is the first of its kind in the UK.
'Mission Is...The Big Question?', forms part of CMS's major new 'Mission Is' campaign, and aims to stimulate people's thinking about mission and broaden their perspective of the reality of mission in the 21st century.
The game has been designed for small groups of all ages. Each playing pack includes a selection of 'Mission Is', 'Word' and 'Action' playing cards and players are challenged to construct a defining answer to the question 'What is mission?' using the prompts provided on each card.
Players build their personal statements using locations such as 'foodbank', 'local estate', 'school', or 'home'; different groups of people such as 'homeless people', 'my mates' 'work colleagues' or 'prisoners' and varying actions such as 'visiting', 'helping' or 'baking', as well as more traditional interpretations of mission such as 'preaching', 'going' and 'church'.
Finally, the group of players are asked to vote on the most exciting 'Mission Is' statement from the different hands displayed throughout the game.
CMS's executive leader, Philip Mounstephen, explained the motivation behind creating the game: "Our central belief is that all of God's people are called to join in God's mission yet we suspect many people's narrow definition of what 'mission' really means, is a major contributor to their hesitation about getting involved.
"This game is a fun way to challenge those misconceptions and broaden people's understanding of how they can be a part of God's mission."
Over this summer, CMS is seeking to start a national conversation on mission by launching a major listening exercise to ask what "Mission Is".
It hopes to hear from thousands of Christians about what their understanding and experience of mission is. Other than the card game, CMS have developed a variety of resources for both individuals and churches including an online survey app, video clips, prayer materials and a virtual retreat.
Mission Is campaign manager, Thomas Fowler said: "Views of mission can range from a universal 'renewal of all things' to baking a cake for my neighbour.
"There's no definitive answer but as we prompt people to consider the question we hope people will be inspired to see God's mission as their mission, and get involved."
