GUILFORD, Conn. (AP) _ Everett R. Clinchy, founder and former president of the National Conference of Christians and Jews, has died after a short illness. He was 89.

Clinchy died Wednesday at Branford Hills Health Center, near his home in Guilford, said James E. Pitt, a conference spokesman.

Clinchy, an ordained Presbyterian minister who discouraged the use of his religious title, led a lifelong campaign for cultural democracy in the United States.

He founded the conference in 1928 as a reaction to anti-Catholic bigotry that raged during the presidential campaign of Alfred E. Smith.

The mission of the conference, he once said, was to bring about ''a love for America so great that no one will be able to hate any group in the American neighborhood.''

In 1958, Clinchy left the conference to devote his time to World Brotherhood, which had been a branch of NCCJ.

World Brotherhood became an independent international effort to promote racial, religious and social understanding. Its co-chairmen were Adlai E. Stevenson, Philippine Ambassador Carlos Romulo, Vijaya Lakschmi Pandit of India and Paul-Henri Spaak, Belgium's foreign minister.

With Stevenson, Spaak and others, Clinchy later formed the Council on World Tensions to assist in the search for solutions to international conflict.

In 1963, Clinchy created the Institute on Man and Science in Rensselaerville, N.Y., as a place where scientists and educators could study the relationship of scientific and economic achievements to human needs.

Clinchy retired from the conference in 1972, when he was 75, but continued his mission. In 1980, he launched ''Islam and the West,'' a program to foster understanding between Christian and Muslim cultures.

Clinchy is survived by his wife, Winifred Mead Clinchy, a son, two daughters, a sister, a brother, 12 grandchildren and four great-grandchildren.

A memorial service will be held in the spring.
