In addition to the political defense of the church, liturgical reforms, anti-modernism, and the beginning of the codification of canon law, the papacy of Pius X saw the reorganisation of the Roman Curia.
He also sought to update the education of priests, seminaries and their curricula were reformed.
In 1904 Pope Pius X granted permission for diocesan seminarians to attend the College of St. Thomas.
He raised the college to the status of Pontificium on 2 May 1906, thus making its degrees equivalent to those of the world's other pontifical universities.
By Apostolic Letter of 8 November 1908, signed by the Supreme Pontiff on 17 November, the college was transformed into the Collegium Pontificium Internationale Angelicum.
It would become the Pontifical University of Saint Thomas Aquinas, Angelicum in 1963.

Pius X published 16 encyclicals; among them was Vehementer nos on 11 February 1906, which condemned the 1905 French law on the separation of the State and the Church.
Pius X also confirmed, though not infallibly, the existence of Limbo in Catholic theology in his 1905 Catechism, saying that the unbaptized "do not have the joy of God but neither do they suffer... they do not deserve Paradise, but neither do they deserve Hell or Purgatory."
On 23 November 1903, Pius X issued a papal directive, a motu proprio, that banned women from singing in church choirs (i.e. the architectural choir).

In the Prophecy of St. Malachy, the collection of 112 prophecies about the popes, Pius X appears as Ignis Ardens or "Burning Fire".

In November 1913, Pope Pius X declared tango dancing as immoral and off-limits to Catholics.
Later, in January 1914, when tango proved to be too popular to declare off-limits, Pope Pius X tried a different tack, mocking tango as "one of the dullest things imaginable", and recommending people take up dancing the furlana, a Venetian dance, instead.
