Justin Martyr was a Christian apologetic author who eventually sacrificed his life for his faith. He experimented with several schools of philosophy before converting to Christianity. Justin’s philosophy offered a sort of marriage of Greco-Roman philosophy with Christian theology. He was considered an apologist because he defended Christianity by using philosophers commonly accepted by pagans, especially Plato, to support the ideals of Christianity.
In Justin’s Dialogue with Trypho, he discusses how, under a Platonist, he refined his skills in the realm of philosophy with each day. “…in the company of a wise man who was highly esteemed by the Platonists…I forged ahead in philosophy and day by day I improved” (Bart D.

Ehrman, After the New Testament: A Reader in Early Christianity, p. 20). This statement also supports the idea of there being one God, instead of, the polytheistic beliefs of the pagans.
Justin sites the philosophies of Plato to support the Christian belief in monotheism. “’But the Deity, father,’ I rejoined,’Cannot be seen by the same eyes as other living beings are.

Justin, supported by Plato, argues that there is one God. He is not a physical being, but one that is spiritual. We are connected to God through our beliefs that we hold in our hearts and minds.
