聖公宗使命標記簡介
A Brief Introduction to “Five Marks of Mission”
五大使命標記已在聖公宗及其他基督宗教傳統中得到廣泛認可，並為世界各教堂/牧區和教區提供了一份實用且易於記憶的宣教活動「清單」。使命標記並非關於宣教/使命的終極而完整的陳述，但為群體提供了實用指南去了解宣教使命的整全性。
首四個標記最初由第6屆普世聖公宗諮議會 (ACC-6) 於 1984 年制定。(參見1984年第6屆普世聖公宗諮議會報告《愛的繫連》第49頁）
第五個標記於 1990 年新增。當時，第8屆諮議會 (ACC-8) 認識到創造和環境危機所帶來宣教學上意義和理解《聖經》意義，並決定制定一個新的標記來體現這種理解。在採用第五個使命標記時，第8屆諮議會表示：「我們現在認為，我們理解到生態危機，實際是對所有受造物合一所面臨的威脅；這意味著我們必須添加第五個肯定。」（參見1990年第8屆普世聖公宗諮議會報告《破碎世界中的使命》第101頁）
自那時起，隨著普世聖公宗朝著以使命為中心的方向前進，我們理解五大使命標記須與時並進 (dynamic)，並定期審視。為此，在2012年於新西蘭奧克蘭舉行的第15屆諮議會修訂了第四標記的用詞。
The Five Marks of Mission have won wide acceptance among Anglicans and other Christian traditions and have given parishes and dioceses around the world a practical and memorable “checklist” for mission activities. They are not a final and complete statement on mission but they offer a practical guide to the holistic nature of mission.
They were first developed as four marks by the Anglican Consultative Council (ACC-6) in 1984. (See Bonds of Affection-1984 ACC-6 p49.)
A fifth was added in 1990 when, having appreciated the missiological and biblical implications of the creation and environmental crisis, ACC-8 decided that a new mark of mission that captured this understanding was inevitable. In adopting this fifth Mark of Mission, ACC-8 stated: “We now feel that our understanding of the ecological crisis, and indeed of the threats to the unity of all creation, mean that we have to add a fifth affirmation.” (See Mission in a Broken World-1990 ACC-8 p101.)
Since then, it has become clear that as the Anglican Communion travels along the road towards being mission-centred, the Five Marks need to be understood as dynamic and should be reviewed regularly. To this end, the wording of the Fourth Mark was revised by ACC-15 in Auckland, New Zealand in 2012.
