In Paul what is pointed out theologically was also brought about physically: healed of his inner blindness, he sees clearly. Thus St Paul was not transformed by a thought but by an event, by the irresistible presence of the Risen One whom subsequently he would never be able to doubt, so powerful had been the evidence of the event, of this encounter. It radically changed Paul’s life in a fundamental way; in this sense one can and must speak of a conversion. This encounter is the centre St Luke’s account for which it is very probable that he used an account that may well have originated in the community of Damascus.
