The Anti-Defamation League of B'nai B'rith is forming a special task force to investigate and combat the activities of Nazi war criminals in the United States.

The task force will be guided by Elliot Welles, a concentration camp survivor who will maintain contacts with organizations of Holocaust survivors throughout the world and monitor information and activities related to Nazi war criminals in this country and elsewhere in the world.

A missionary conference that was to have brought Prime Minister Ian Smith and other Rhodesian leaders to an independent suburban Chicago church last weekend has been indefinitely postponed.

The Rev. Paul Lindstrom of the Church of Christian Liberty, long associated with right-wing causes, said that Smith, as well as Rhodesian Methodist Bishop Abel Murora, were unable to come to the session, which had been announced for July 29.

Lindstrom, who once burned a Communist Chinese flag on the church altar during a worship service to demonstrate his anti-Communism, had announced the conference in mid-July, with a simultaneous confirmation from the Rhodesian government. His announcement came on the heels of the massacre of missionaries in Rhodesia. Lindstrom has proposed opening a mission in the troubled country that would feature a corps of Vietnam War veterans as security guards.

Ugandan President Idi Amin, who is widely believed to be personally responsible for the assassination two years ago of Anglican Archbishop Janani Luwum, has sent a message to the bishops attending the worldwide Lambeth Conference in England offering to host their next meeting.

In a message conveyed by Luwum's successor, Archbishop Silvanus Wani. Amin suggested to the assembled bishops that "this is a time for reconciliation based on love "and that he yearned to "reestablished old reletionships."

Archbishop Donald Coggan of Canterbury, titular head of the worldwide Anglican community, was said to have received the Ugandan communication "with grave courtesy" but has made no comment on it.

Christian academies battling North Carolina law requiring proof to the state of their educational prowess, got on comfort from long-time parochial school administrators.

Lutheran and Roman Catholic educators testified in court that state laws requiring certified teachers, approved textbooks and compliance with other state standards such as the length of the school year in no way interfered with the imparting of religious values.

Eleven of the academies, operated largely by theologically conservative Protestant groups, have been called into court for failing to file statemandated reports on their operations.

The academy's sponsoring churches contend the schools are an extension of their religions ministries and are constitutionally protected from government interference. The state has withheld accreditation from the academies, which legally makes the children who attend them truants.

A Montgomery, Ala., judge has ruled that loyalists in a congregation that broke from the Presbyterian Church in the U.S. remain the rightful owners of the church property.

The case originated in 1973, where Trinity Presbyterian Church voted 814 to 112 to pull out of the PCUS, more commonly called the Southern Presbyterian Church, and switch to a body now known as the Presbyterian Church in America.

County Judge G.H. Wright Jr. upheld the ruling of the 1976 PCUS General Assembly, which stated that rules established by the Montgomery Presbytery for churches wishing to leave the denomination were unconstitutional.

Judge Wright, who took the case after all other Montgomery judge excused themselves on grounds that they were Presbyterians, based his ruling on a U.S. Supreme Court decision that held that civil courts must accept the decision of the highest ecclesiastical body of a denomination.

Twenty six national religious leaders - Protestant, Catholic, Jewish, Orthodox, and Mormon - met with President Carter this week, at his request, and expressed their support for U.S. development aid for the poor around the world . . . The University of Notre Dame ranked first among Catholic and 20th among all institutions of higher learning in the amount of financial gifts - 12 million - received during the last academic year. Harvard, predictably, with a take of more than $74 million, led the list of all institutions, with Stanford - $56 million - second . . . The Christian Church (Disciples of Christ) has 9.7 per cent fewer clergy and 21 per cent fewer members today than it did a decade ago . . .

The Baptist World Alliance condemned conflicts in central and southern Africa, endorsed disarmament upheld freedom of religion and called on all governments to "take all necessary steps to correct injustices, to liberate untried prisoners and to desist from all denials of human rights." The body, which met in Manila, did not say which countries their resolution was aimed at.
