The Evangelists' towers will be surmounted by sculptures of their traditional symbols: a bull (St Luke), an angel (St Matthew), an eagle (St John), and a lion (St Mark). The central tower of Jesus Christ is to be surmounted by a giant cross; the tower's total height (170 m) will be one metre less than that of Montju´c, as GaudÝ believed that his work should not surpass that of God. Lower towers are surmounted by communion hosts with sheaves of wheat and chalices with bunches of grapes, representing the Eucharist.
Themes throughout the decoration include words from the liturgy. The towers are decorated with words such as "Hosanna", "Excelsis", and "Sanctus"; the great doors of the Passion fašade reproduce words from the Bible in various languages including Catalan; and the Glory fašade is to be decorated with the words from the Apostles' Creed.d.
