The Council of Trent’s variation makes sense because – after the loss of the Paleolithic Lebenswelt – humans can only experience disorientation and alienation in the Lebenswelt of unconstrained complexity. By definition, “we know no what we do” because we do not even realize that we are creating symbolic orders – “languages” – all the time, without constraint. We cannot predict the consequences of the social constructions that arise from these “languages”.
So we must rely on Sanctifying Grace – particularly the orientation that comes from the Revelation of God that is the Bible – plus the inspiration that comes from the Sacraments as Living Expressions of that Revealed God – in order to transform our actions to be in accord with His Will. Yet, these actions are not prescribed. We are free to create. We are encouraged to create.
In sum, we need an orientation in order to properly (and generatively) mould our intellects and wills.
