Abstract
The aim of this chapter is to reconstruct a hypothetical genealogy of the U.S. national motto “in God we Trust” by comparing the juridical and theological concept of “depositum”. According to Philo of Alexandria, the deposit was the most sacred institutional act of ancient social life, because it had both a religious and a sociological function. According to the Epistulae to Timothy the term ‘deposit’ defined the legacy of the Christian faith of which the disciple of St. Paul was entrusted. His task was to manage this legacy and to spread it among the others. Hence the deposit defined at the same time a contract based upon good faith and a symbolic space of “security”, namely a container that protected an unchangeable content: the oral knowledge transmitted by Christ to the Apostoles and, indirectly, to St. Paul. The depositum was also the procedure through which the word of Christ would acquire all its potential. On the other hand, the contract defined as “depositum” by Roman law was characterized by a centrality of the so-called bona fides and by the distinction between regular and irregular deposit. This means that the principle of good faith should lead the conducts of the manager whose task is exactly to look after an object called Christian faith. How can we interpret the word ‘trust’ according to the juridico-political remarks? The purpose of this chapter is to explain all these related issues.
