Pope Paul VI issues the Credo of the People of God.

Pope Paul VI was head of the Catholic Church and sovereign of the Vatican City State from 21 June 1963 until his death on 6 August 1978. Succeeding John XXIII, he continued the Second Vatican Council, which he closed in 1965, implementing its numerous reforms. He fostered improved ecumenical relations with Eastern Orthodox and Protestant churches, which resulted in many historic meetings and agreements. In January 1964, he flew to Jordan, the first time a reigning pontiff had left Italy in more than a century.

Solemni hac liturgia is a motu proprio issued by Pope Paul VI on 30 June 1968. Its content substantially consists of a creed known as the Creed of the People of God.

June 30 is the 181st day of the year in the Gregorian calendar; 184 days remain until the end of the year.
