Ancient Florence is described by Cacciaguida as the epitome of a good society, whose political priorities are pure. Here is a society whose life centers on Christianity, as evidenced by the "walls" which surround a church clock tower marking the canonical hours of "tierce and nones." The women of Florence are not concerned with fancy clothes or makeup, but with raising children. And families are concerned only with raising their children prudently and arranging proper marriages for their virtuous daughters.
One of the major motifs of Paradiso is that the rituals of the past are often thought superior to those of the present. The Florentine families are no exception; in ancient Florence, they were "acclaimed and just," but in the present-day Florence, they are corrupt, (i.e. dividing into political factions, inverting the noble standard of Florence (the lily), and staining their symbolic lily red with the blood of their brothers).
The Church has brought a whole new level to political corruption: waging war on the virtuous and denying people the "bread / the tender Father would deny to none." By "bread" Dante means the Sacraments, the first steps towards repentance for one's sins.
