On the right of the main entrance is the fourth door, made by Venanzio Crocetti (1965), called the "Door of the Sacraments". It is 7.43 m. high and 3.80 m. wide, and consists of two leaves of four panels each. These show the seven sacraments, signs of the faith and sources of grace, actions with which Jesus saves us. In the panels on the left: the angel announces the grace of the sacraments: Baptism, Confirmation and Penance; in the panels on the right: the Eucharist, Marriage, Holy Orders, and the Anointing of the Sick.

In 1966 he (Paul VI) also inaugurated the Door of Sacraments, completed by Venanzio Crocetti after 13 years of work, with eight panels, framed like paintings, each representing the celebration of every Sacrament. Complying with the balanced distribution of the equal-sized compartments, the artist created a plastic and expressive decorum and a simple narrative style, based on familiar, contemporary, everyday events.
