In 1938 a Christian community magazine "Masihi Mazdor" was published by young seminary students Kundan Lall Nasir, and Basher S. Amam Din from Sargodha with the aim of protesting against the controversial Christian Personal Law introduced by the British India government. Later this magazine became the voice of British Indian Christian Community. However it was banned by the Government of Pakistan
in mid-Fifties. It continued under a new name "Masihi Khadam" till 1965 when the Qadiani community then accepted as Muslims forced the government of Pakistan to ban this magazine too. Anticipating the ban on "Masihi Khadam" declaration for "Kalam-E-Haq" was taken and the first issue of "Monthly Kalam-E-Haq" was published in January 1966. Since then it is being published regularly though from August 1994 till May 1995 due to negligence of some of the members of editorial board the magazine could not be published. In June 1995, the administration of Faith Theological Seminary Gujranwala, and the Synod of the United Presbyterian Church of Pakistan started reprinting of this most popular and informative magazine.
