Read John 13:35 and 1 John 4:21. What do these passages reveal about Satan’s challenge against the government of God in the great controversy? What do they tell us about the essence of genuine Christianity?

 Love was the norm of Christian communities in the first few centuries. Tertullian, an early Christian theologian, claimed: “It is mainly the deeds of a love so noble that lead many to put a brand upon us. See, they say, how they love one another.”—“Chapter 39,” in Apology, trans. S. Thelwall, https://www.logoslibrary.org/tertullian/apology/39.html (accessed October 10, 2022).

 One of the greatest revelations of God’s love was demonstrated when two devastating pandemics plagued the early centuries around a.d. 160 and a.d. 260. Christians stepped forward and ministered to the sick and dying. These plagues killed tens of thousands and left entire villages and towns with scarcely an inhabitant. The unselfish, sacrificial, caring, loving ministry of Christians made a huge impact on the population. Over time, thousands, and eventually hundreds of thousands, and then millions in the Roman Empire became believers in Jesus during these two epidemics. Love, outgoing concern, and organized, selfless care of the sick and dying created an admiration for these believers and the Christ they represented.

 Rodney Stark’s The Rise of Christianity is a modern historical narrative portraying these historic events in a new and improved light. In it he describes how during the second epidemic the whole Christian community, which was still heavily Judeo-Christian, became a virtual army of nurses, providing the basic needs for the suffering community to survive.

 “At the height of the second great epidemic, around a.d. 260, . . . Dionysius wrote a lengthy tribute to the heroic nursing efforts of local Christians, many of whom lost their lives while caring for others.”

 “Most of our brother Christians showed unbounded love and loyalty, never sparing themselves and thinking only of one another. Heedless of danger, they took charge of the sick, attending to their every need and ministering to them in Christ, and with them departed this life serenely happy; for they were infected by others with the disease, drawing on themselves the sickness of their neighbors and cheerfully accepting their pains.”—The Rise of Christianity (Princeton, NJ: Princeton University Press, 1996), p. 82.
