The name Villazar is a contraction of Villafuerte and Zalasar, family names of the two most prominent families in the place.   It was erected as a parish by virtue of a decree issued by His Grace, Most Rev. Pedro P. Santos, D.D., Archbishop of Caceres in July 4, 1956.

     The parish has for its patron saint, Saint Pius X.

     The creation of a parish was necessitated by the increasing population of the parish of Sipocot, of which Villazar was originally a barrio.   The distance of the place and the needs of other places prevented the proper and adequate pastoral care of the people living in Villazar and neighboring barangays.   So this parish was created. Included within its ecclesiastical jurisdiction are the following barangays: Villazar, Calagbangan, Bigaan, Tula-tula, Sooc, Napolidan, Alanao, Pulang-tuna, Haluban, Bahe, Bolaguin, and Buenasuerte.

     The first parish priest was Very Rev. Domingo Halum.   He built the church and the convent.

Kami, sa Parokya ni San Pio X, sa tahaw kan kadakul na kayamanan nakakamate nin grabeng pagtios sa salang paggamit kan mga biyaya nin kapalibotan, mayong pagkasararo, kulang sa pagkasabot asin maluyang pagtubod.

Nagmamawot nin sarong komunidad nin mga kristiyano na may pagkasararo asin may pagkaminorootan sa pakisumaro ki Kristo sa dalan nin kabanalan, talingkas sa gabos na klaseng pang-aapi orog na sa mga daing sukat asin may pagkamakulog sa mga biyaya nin kapalibutan para sa maogmang pagbuhay-buhay.

Tanganing magkaigwa nin katotoohan an gabos na ini, sa inspirasyon ni Maria, samuyang ina asin sa tabang ni San Pio X, samong patron, kami minadusay:

-sa buhay na pagbalangibog kan Marhay na Bareta na may makahulugan na pakikisumaro sa tunay na kamatean kan kasaraditan.

-asin sa pagpasabot kan tamang paggamit nin biyaya nin kapalibotan.
