Summary:R.D. studies texts from 'De civitate dei' concerning the human condition, indicating tensions in man's life as citizen and as believer. The model of human activity is the communion of saints, although the need to prevent injustice cannot be overlooked. R.D. justly concludes in A.'s words from 'De civitate dei' XIX, 19 regarding the need for balance between earthly good and final destiny: Nec sic esse quisque debet otiosus, ut in eodem otio utilitatem non cogitet proximi, nec sic actuosus, ut contemplationem non requirat dei.
