Born in thirteenth-century Italy, Thomas Aquinas joined the Dominican Religious Order Today he is recognised as one of the greatest theologians of the Middle Ages. Thomas taught that reason can lead us to believe in ‘a God’, but only revelation can show us God as He really is.
Thomas Aquinas once wrote: ‘Three things are necessary for the salvation of man: to know what he ought to believe, to know what he ought to desire, and to know what he ought to do.’
For Aquinas, right beliefs were insufficient. Right beliefs and right action were also insufficient. It is the transformation of our desires – the inner orientation of our hearts, tied with belief and action – that are demonstrations of the life of God within us.
