Autor se u ovom istraživanju u trima cjelinama bavi promjenom paradigme u kasnoantičkom svijetu u poimanju bolesti. Najprije će istražiti pristup bolesti u antici i kasnoj antici kada su dominirala dva osnovna pristupa: medicinski i religijski (poganski, mitološki). U drugoj cjelini bavi se teorijama o uzrocima bolesti, pri čemu je imao potrebu istaknuti tri temeljna načina njihova tumačenja: filozofski, medicinski i religijski. Posljednje poglavlje posvetio je istraživanju kršćanskoga stava prema bolesti, prateći tekstove i svjedočanstva svetih otaca u prvih nekoliko stoljeća. Svoje tvrdnje rasporedio je u tri dijela: najprije je pokušao odgovoriti na pitanje što je bolest i koji su joj uzroci iz kršćanske perspektive, potom je nastojao definirati ulogu Boga u liječenju bolesti, a naposljetku je istaknuo ulogu Krista kao liječnika prema poimanju u ranokršćanskoj teologiji. Glavni je autorov zaključak da su kršćani napravili najveću promjenu paradigme i životnih stavova prema medicini zahvaljujući drukčijem poimanju Boga, a sve što je bilo u skladu s njihovom svijesti o Bogu ostalo je nepromijenjeno. Upravo zato nisu osporili ni filozofiju ni medicinu kao znanost, premda su napravili određene zaokrete i unijeli novosti. The author of this research, in three units, deals with the change of paradigm in the world of late antiquity in understanding illness. First, he examined illness in antiquity and late antiquity, which were dominated by two basic approaches: medical and religious (pagan, mythological). The second chapter deals with theories regarding the causes of illness, where the author highlights three fundamental ways of their interpretation: philosophical, medical, and religious. The last chapter is dedicated to studying the Christian attitude toward illness, following the texts and testimonies of the holy fathers in the first few centuries. The author arranged his claims in three parts: first, he tried to answer the question of what illness is and what are its causes from a Christian perspective; then, he tried to define the role of God in treating illness; and finally, he emphasized the role of Christ as a physician as understood in early Christian theology. The author’s main conclusion is that Christians made the biggest change in paradigm and life attitudes toward medicine thanks to a different notion of God, and everything that was in accordance with their awareness of God remained unchanged. That is why they did not challenge philosophy or medicine as a science, although they made certain shifts and introduced innovations.
