(How far must the so-called Hierarchical Church dip her fingers, if at all, into the realm of temporal politics? From the wars of ancient Europe to the lessons of liberation theology, Resurgent contributor Carlo de Leon offers the historical basis for the Philippine church to keep herself off the Duterte Administration's mortal struggles.)
The Congress of Vienna was convened in 1815 by the European nations that defeated Napoleon Bonaparte to establish a new balance of power in Europe and prevent a resurgence of Napoleonic imperialism. The secondary reason was to prevent political revolutions such as the French revolution and the preservation of the status quo.  Shortly after this meeting, Russia, Austria, and Prussia, formed the so-called “Holy Alliance of Throne and Altar”.
This alliance is a “Gallican” absolutist formula characterized by sovereign power or ultimate authority in the state vested in the hands of a king who claimed to rule by divine right. It is the belief that civil authority represented by monarchs and other state rulers have similar powers as the Pope and the Church.  This makes their power absolute in spiritual and temporal matters.
Pope Leo XIII spent a lot of energy to disengage the Church from sectarian liberalism by confining the Church’s work to the sacristy, as had been done earlier by Pope Pius IX. Until the 20th century, the Gallican absolutist’s formula likewise haunted St. Pope Pius X, who had to disengage attempts of socio-political movements such as the Francaise and Le Sillon in France who were demanding to politicize the Church, using it for their temporal goals and other selfish interests. 
Happening in our time
We also witnessed St. Pope John Paul II's resolute efforts to disengage the Church from repeated attempts of "liberation theologies" to commit the Church to socialism, an endeavor that communist totalitarian dictators have been doing with their "patriotic churches". The Church is a supernatural institution that should be free from entanglement with secular or worldly institutions or movements. 
According Fr. Joseph M. de Torre (author, political philosopher and Roman Catholic priest), “The Church is not ‘of this world’ and therefore cannot be politicized or nationalized”. He further underscored that "The Church cannot therefore be the 'middle way' between any ideologies or economic or political systems, simply because she operates on a different level, namely the strictly moral and religious level, which is not temporal as such, or subject to change and pluralism.” Clearly, the Church and its leaders cannot interfere in the domestic politics of a nation; they should stick to matters of faith and morals, which is their real vocation.
It bothers me no end every time I see members of the clergy, religious congregations, and bishops, priest and nuns, engaging themselves in partisan politics by supporting one particular view, implicitly curtailing the right to plurality of opinions on temporal and worldly matters. It continues to bother me, even more, when I observe that Catholic teachings are no longer given emphasis by some Church leaders. They appear to downplay the importance of the Catechism and Christian Doctrine, in favor of political advocacies of particular groups that, they argue, are more important than teachings in relation to the practice of the faith. At the very least, while they are convinced they are doing a good job, one can observe that most Catholics continue to have a shallow understanding of their faith—a sad and urgent reality that needs to be addressed.
