In this article a study is made of the concept �oikodome� and its derivatives in the New Testament and early Christianity. Hence, in this essay the focus is limited to the use of the term οἰκοδομέω/οἰκοδομὴ(ν) in the New Testament, and briefly turns to inspiring trajectories in early Christianity. A detailed focus on the term(s) reveals the complexity of the matter in the different Biblical contexts with its multi-layered dimensions of meaning. Subsequently, attention is turned to a study of 1 Thessalonians, followed up with a discussion of the trajectories of other-regard and radical self-giving love in the early Church as witnessed by insiders and outsiders in antiquity.
