The Church of North India (CNI) was formed in 1970 when six denominations came together with the threefold aim of 'Unity, Witness and Service'.

Today, CNI has some 1.3 million members in 3,000 congregations spread over 26 Dioceses that cover two-thirds of India's (Northern) land area.

PCI links with CNI are mainly through the Gujarat Diocese, where Rt. Rev. Silvans Christian is Bishop. The Diocese seeks to reach out in mission and evangelism wherever possible, while also working to establish new worship centres; train men and women for evangelism and the pastoral ministry; and bringing Christians together from different traditions. 

At Synod level, PCI normally sends a representative to CNI's biennial 'Partners-in-Mission' meetings, allowing participants to meet and share fellowship with local members of CNI as well as leaders from the hosting Diocese.
