The Trinitas Study Center is a Christian education service designed to assist homeschooling parents and their high school students in the western Pennsylvania area.

Formerly called “Grove City Christian Academy Study Center” and begun in 2009, it is under the administration  of Grove City Christian Academy’s board of directors.


The Trinitas Study Center seeks to instruct children concerning the sovereign Lord of creation, the purpose He has for them, and the nature of the creation over which He has placed man.  We strive to equip and assist children to faithfully and obediently carry out man’s God-given task in Genesis 1:28: “God blessed them and said to them, ‘Be fruitful and increase in number; fill the earth and subdue it.  Rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground.'”  We want their convictions and beliefs regarding the whole of life to be rooted in the Bible.  While striving for academic excellence in every discipline, Trinitas emphasizes a structured integration of our Christian world and life view in all of our studies.  We seek to reinforce the moral values and Christian faith that our students are taught in the home and church.

Why “Trinitas”?

“Trinitas” is the Latin word for “trinity,” coined by Tertullian to explain the relationship between the Father, Son, and Holy Spirit.

All the questions regarding our existence and knowledge are answered and find meaning in the trinity.   Not only was creation an act of the Trinity, but so is our redemption. The Father planned our redemption, Christ accomplished our redemption, and the Spirit applies the redemption to us!  In effect, all of life finds its basis and meaning there.

This is a fitting name for a Christian study center. All of our courses are based in the Trinity: the sciences because the Trinity is our Creator; composition, communication and languages because we are made in the image of the One who communicated to Himself and to His creation; math because the Trinity is a God of order; and history/literature because it reviews God’s historical providence and addresses the efforts of those who explain the world in light of the Trinity and others who do not.
