Abstract
This article examines the notion of providence in the thought of St Justin martyr. First, it is shown the relevance of the question for St Justin, since it was an important topic in his time. Secondly, the comparison to the philosophical context provides a more complete view of St Justin’s position. Thirdly, the notion of providence is considered in the whole of St Justins’ thought. So, the author can conclude that Christian philosophy requires a particular providence which nevertheless allows human and angelic free will. The history of salvation plays also an essential role in the understanding of providence, because some past and future facts (such as original sin or Incarnation) condition the choices of providence at the present.
