The Reverend Tara Curlewis, general secretary of the NCCA said “Harvey Perkins assisted the churches to embrace Unity encouraging churches to work together locally and regionally. He helped facilitate conversations in South Australia that led to the formation of the South Australian Council of Churches.”

“He had a deep passion for the unity and mission of the church and identified that there was much that could be learnt from the Asian Church.”

Ms Curlewis concluded “He has left a large ecumenical footprint for which he will be long remembered. Today we give thanks to God for his ministry and uphold his family in prayer as they mourn his passing.”
