On July 15, 1968, Paul VI named Mugavero as the fifth bishop of Brooklyn. Mugavero often called Brooklyn "the diocese of immigrants," and was proud that mass was celebrated there in 14 languages. By 1985, the Nehemiah Project had constructed 300 row houses in the
Brownsville section of Brooklyn at an average cost of $51,000. The project sold the homes to families with incomes averaging less than $25,000. In 1970,
Veronica Lueken, a resident of the
Bayside section of Queens, claimed to have seen her first
apparition of the
Virgin Mary. Over the next 25 years, she reported more apparitions of Mary, along with those of Jesus Christ and some of the saints. Lueken reported receiving messages criticizing the changes from the
Second Vatican Council, the revival of the
permanent diaconate and other reforms in the Catholic Church. In 1986, Mugavero issued a declaration concerning Lueken's visions; "I, the undersigned Diocesan Bishop of Brooklyn, in my role as the legitimate shepherd of this particular Church, wish to confirm the constant position of the Diocese of Brooklyn that a thorough investigation revealed that the alleged "visions of Bayside" completely lacked authenticity".In 1987, Mugavero established the Immaculate Conception Center at the site of the former Cathedral College. Mugavero was a founder of the Campaign for Human Development, an annual fund-raising drive in the diocese for the poor. ==Retirement and legacy==
