Alfredo Verzosa y Florentín (9 December 1877 – 27 June 1954) was the fourth native Filipino to be elevated as Bishop of the Roman Catholic Church and the first from Northern Luzon.

He co-founded the Congregation of the Missionary Catechists of the Sacred Heart (MCSH), which focuses on education and administration within the church, especially catechesis.

The Ilocano priest Gregorio Aglipay served as Military Chaplain for Emilio Aguinaldo's Revolutionary Government, and was later excommunicated for Usurpation of Jurisdiction after attempting to secure control of the Nueva Segovia diocese.

During his missionary work, he faced opposition, including a reported incident where a spear thrown by a minister of another sect killed his horse.

[4] Drawing on his experience in Nueva Segovia, Verzosa prioritized catechetics in Lipa, establishing centers and training local catechists.

He also introduced various religious congregations to the diocese, including the Carmelites and the Pauline Fathers and Sisters, and oversaw the construction of schools, seminaries, catechetical centers, and convents.

In January 1926, a rebellion among native priests in Pangasinan, led by Hurth's suspended Vicar General, Benigno Jimenez, created a crisis.

Verzosa assumed leadership of Nueva Segovia in February 1926 and addressed the Pangasinan crisis through personal visits, discussions with clergy, and retreats.

Also in 1926, Verzosa arranged for the Divine Word Fathers (SVD) to take over the Vigan Seminary after the Jesuits declined to renew their contract.

He was known for his financial support of priests from poor parishes, his commitment to celibacy, and his dedication to helping students finish their studies.

He lived simply, prioritizing diocesan funds for building churches, convents, monasteries, and schools rather than personal comforts.

In 1944, Verzosa requested assistance from the Holy See, leading to the appointment of his Vicar General, Alfredo Obviar, as his Auxiliary Bishop.

Due to declining health, Verzosa was relieved of his duties as Ordinary of Lipa in 1949, with the diocese placed under Apostolic Administration led by Bishop Rufino Santos.
