The Diocese of Lipa was created on April 10, 1910, separating it from that of Manila under the supervision of Pope Pius X and with Giuseppe Petrelli as its first bishop.

About a month later on April 25, the Prelature of Infanta was created, comprising the remaining part of Quezon, including the Polillo Islands and what is now the province of Aurora.

It was during his term that the Diocese of Lipa, on June 20, 1972, became the country's tenth archdiocese and ecclesiastical province by order of Pope Paul VI of the papal bull Qui Sumi Nominis.

During his incumbency Vidal organized the Pastoral Council, and initiated the construction of the Lipa Archdiocesan Formation Center.

[3] With the resignation of Cardinal Jaime Lachica Sin in 2003, Rosales was chosen by Pope John Paul II to be the Manila's new prelate, leaving the See of Lipa under the apostolic administration of its Auxiliary Bishop Jose Paala Salazar (d. May 30, 2004).

On May 14, 2004, Pope John Paul II appointed Bishop Ramon Cabrera Arguelles of the Military Ordinariate of the Philippines, another native of Batangas City as the fifth Archbishop of Lipa.

He is a strong opponent of the passage of RH Law, the operation of motorist lodges in the province, the possible mining activities in the municipality of Lobo, and the construction of a coal-fire power plant in Batangas City.

The two white long-stemmed lilies are symbols of Saint Joseph, head of the Holy Family, to whom the faithful of the diocese are ardently devoted.

The province's land area is 3,165 square kilometers (1,222 sq mi) and the population as of the 1994 census is 1,668,480 of which 99.5 per cent are Catholics.

The archbishop also oversees the suffragan dioceses of Boac, Gumaca, Lucena, Prelature of Infanta, and also serves as de facto overseer of the apostolic vicariates of Calapan, and San Jose.

On August 18, 1995 after much review, and meetings presided over by Archbishop Gaudencio Rosales himself, the archdiocese's vision was conceived: A people of God called by the Father in Jesus Christ to be communities of totally developed human persons in the world, witnessing to the Kingdom of God by living the Paschal Mystery in the power of the Holy Spirit.
