VIRGÓ SACRÁTA is a Christian mission-driven online resource and shop inspired from the beauty of Catholic faith, tradition, and arts. Our mission is to “Restore All Things to Christ!”, in continuing the legacy of Pope St. Pius X under the patronage of the Blessed Virgin Mary. “Who is she that cometh forth as the morning rising, fair as the moon, bright as the sun, terrible as an army set in battle array?” O Mary, conceived without sin, pray for us who have recourse to Thee.
