In his Summa, St Thomas develops the Augustinian idea of peace. It is no coincidence that he deals with this in relation to the theological virtue par excellence — which is charity — of which peace is an effect. True peace exists where there is true love of God and neighbour, something which can only come about in the soul in a state of grace. He concludes by stating that “without sanctifying grace, peace is not real but merely apparent” (Summa Theologiae, II-II, q. 29, a. 3, ad 1).
