Generally, Apologists, because their job description entails the defense of the faith, their works are generally reactive to the charges of the non-believers. Justin’s responses are no different in this aspect, from D’ambrosio we learn that the calumny of the day expressed charges of incest and cannibalism, “Rumors had arisen, based on Christians’ terminology, that their secret meetings were “love feasts” between “brothers and sisters” who “consumed the flesh and blood of a man called Christus.” These types of accusations continue through St. Augustine’s day to our present “meme” culture. The First Apology starts off, as D’ambrosio explains, “by blasting the idolatry and sexual immorality of the pagan society of his day…adultery and promiscuity, including homosexual liaisons and pedophilia, were rife in the empire at this time.” By studying Church history, we learn that the culture of “free love” or the modern version “love is love” brought forth by the sexual revolution of the late 60s is not a result of modern progression from the dark ages, but rather, a regression to the pagan moral system of hedonism.
Justin challenges the majority culture of the day with a polemical response accusing the pagan faithful of immoral behavior as exhibited in D’ambrosio’s book:
“as for us, we have been taught that to expose newly-born children is the part of wicked men; and this we have been taught lest we should do any one an injury, and lest we should sin against God, first, because we see that almost all so exposed (not only the girls, but also the males) are brought up to prostitution…And you receive the hire of these, and duty and taxes from them, whom you ought to exterminate from your realm. And any one who uses such persons, besides the godless and infamous and impure intercourse, may possibly be having intercourse with his own child, or relative, or brother. And there are some who prostitute even their own children and wives, and some are openly mutilated for the purpose of sodomy; (1 Apology 27.)
St. Justin also by discrediting the accusations of incest by Christians gives a magnificent opus of the purity and dignity that is exhibited in Marriage founded on Christian principles taught by Jesus Christ himself:
“Concerning chastity, He uttered such sentiments as these: “Whosoever looketh upon a woman to lust after her, hath committed adultery with her already in his heart before God.” And, “If thy right eye offend thee, cut it out; for it is better for thee to enter into the kingdom of heaven with one eye, than, having two eyes, to be cast into everlasting fire.” And, “Whosoever shall marry her that is divorced from another husband, committeth adultery.”4 And, “There are some who have been made eunuchs of men, and some who were born eunuchs, and some who have made themselves eunuchs for the kingdom of heaven’s sake; but all cannot receive this saying.” So that all who, by human law, are twice married,6 are in the eye of our Master sinners, and those who look upon a woman to lust after her. For not only he who in act commits adultery is rejected by Him, but also he who desires to commit adultery: since not only our works, but also our thoughts, are open before God. And many, both men and women, who have been Christ’s disciples from childhood, remain pure at the age of sixty or seventy years; and I boast that I could produce such from every race of men. For what shall I say, too, of the countless multitude of those who have reformed intemperate habits, and learned these things? For Christ called not the just nor the chaste to repentance, but the ungodly, and the licentious, and the unjust; His words being, “I came not to call the righteous, but sinners to repentance.” For the heavenly Father desires rather the repentance than the punishment of the sinner. And of our love to all, He taught thus: “If ye love them that love you, what new thing do ye? for even fornicators do this. But I say unto you, Pray for your enemies, and love them that hate you, and bless them that curse you, and pray for them that despitefully use you.”8
What one finds in St. Justin’s text is a belief system pulled straight from scripture. First and foremost, it indicates the early Christian understanding of Jesus’ concept of what constitutes as marriage, as Justin is responding to the promiscuity of pagan culture. In Matthew Chapter 19, as a response to the Pharisees challenging Christ in regards to Moses’ allowance for divorce, Jesus gives a definition of marriage based on Genesis chapter three. The only indication from Christ for a properly ordered relationship, in accordance to God’s creation, is a relationship ordered by biological compatibility and one predisposed to life, anything other than this type of relationship is one that does not reflect the proper sense of Christian community, but rather, pleasure of each single individual; and therefore, in the most proper sense is not true love.
So, If we compare what we’ve learned from our study of the Didache with the writings of St. Justin Martyr, D’ambrioso articulates that “Justin insists that Christianity is not just a belief system but a whole new way of living.” A Christian must choose either the way of life or the way of death. In many ways, the struggle between the two choices sets up much of the frame work of St. Augustine’s text the City of God. We must ultimately between the City of God or the City of Man while living in the City of Man.
