The Seal of Paco Catholic School is the perspective of a lily, a flower symbolic of purity and unselfish love that is right and beautiful.

The Seal has two colors – royal blue and white.  Royal blue stands for justice and peace that every noble person aspires for.  White symbolizes the way of life every Paconian should lead:  clean, simple and honest living...*

The founding year of the School -- 1912 -- has been included in the logo.  The School motto, NOBLESSE OBLIGE, -- Nobility Obligates -- is also added to remind the students, as well as the graduates, that “your nobility, your dignity is great, and great, therefore, is your responsibility.” (More in the section on the school motto.)

The Jerusalem cross is once again clearly incorporated in the seal but in its upright position. Uncontrolled reproductions of the seal in the past rendered the cross indistinct. The Jerusalem cross used in the School seal resembles that of the flag of the Franciscan custody of the Holy Land.  It must be noted that before the Belgians came to Paco, the parish was under the Franciscans.

The School seal shall always have the 12-point scallops around it.  They represent the 12 apostles and evangelists, teachers in their own rights.  Today, they are represented by the teachers.   The number 12 is also known to signify perfection and unity.

The original seal of the School was a lily designed by Mother Guido SMSA.  The seal used until 2006 was based on the design by the late Ramon Vergara Duque in 1940.  He is a member of Class 1941.  Unfortunately, none of his sketches of the Seal and the original design survived the war.

The redesigned seal was made by Reynaldo A. Mones Class 1971. It was submitted to the Intellectual Property Philippines on 14 February 2005 and was issued a Certificate of Registration last 9 October 2006.
