Piketty:
Indeed, the Church’s efforts to conceptualize and formalize economic and financial laws were especially necessary in ternary Christian societies because the clerical class existed not as a hereditary class but only as an abstract perpetual organization (somewhat like modern foundations, capitalist corporations, and state administrations). In Hinduism and Islam there was certainly no shortage of temples and pious foundations, but these were controlled by powerful hereditary clerical classes. Power over ecclesiastical property thus depended more on personal and family networks than in Christian society, so that there was less need to codify and formalize economic and financial relationships.
So, in a way, the celibacy requirements of the church were sort of egalitarian, in that they prevented in from being dominated by particular families that had accumulated power over the years. (Of course, this was pushed upon the clergy by the nobility, whose powerful families wanted to continue to accumulate power and wealth.) But it contributed to the creation of these eternal entities that themselves hoard power and wealth.
And today, these entities are used by the modern equivalent of the noble families (e.g. the Sacklers) to hoard and protect power and wealth.
