The ceilings of the central nave, seen from the interior, will be crowned by aedicules that will provide support for lights with the initials of the Holy Family. Five thick parabolic shields, placed on either side, will have "Amen" and the words of praise "Al", "le", "lu", "ia", broken up into syllables, written on them. The large columns that support the vaults and the roofs also represent the apostles and the churches of the whole world. The columns dedicated to the apostles St Peter and St Paul are outstanding; they are situated between the crossing and the apse, joining the triumphal arch with the Calvary.
