The Psalms used in the Sialkot Hymnbookwith Convention, as well as hymns in Punjabi and Urdu as Indian songs are widely used in all Protestant churches in the country.
In 1968, as a result of the movement opposing McIntire's Liberal Theology, part of the members split and founded another denomination with the same name "United Presbyterian Church of Pakistan" (UPCP).
[7][8] As such, only the splinter denomination, formed in 1968, continued to use the name "United Presbyterian Church of Pakistan".
The church's emphasis is on the Christian Bible as "the inspired, inerrant, infallible and revealed WORD of GOD".
