The insignia is a symbol of the Patriarchate. It was initially used to mark the documents, bulls, and encyclicals issued by the Patriarch. But now this symbol is identified as the emblem of the Syriac Orthodox Church.
The Patriarchal insignia consist of a Koob uono at the top, a blessing-cross and a crosier beneath it, a key on either side, with a banner at the bottom (see fig >1).
The Koob uono(turban) symbolises the apostolic succession and the spiritual >authority of the Patriarch.
The blessing-cross symbolises the apostolic benediction.The cross also
symbolizes Christ's triumph (Colossians 2:15).
The crosier consists of a pair of serpents facing each other, with a cross between them. It is symbolic of the bronze serpent made by Moses (Numbers 21:8).
The crosier represents the healing power of faith and the new life
The keys denote the power to bind and to loose on earth and in heaven. It is a reference to Mathew 16:18-19. This authority, given to St. Peter, is now vested with the Holy Church by the virtue of apostolic succession.
The name of the holy church, in Syriac and in Arabic, is inscribed in the banner.
There is another version of this insignia (see fig 2). This version doesn't contain the keys and doesn't have the Arabic inscription on the banner. Though the Patriarch uses the complete form of the insignia, both forms are used indiscriminately by the various bodies of the Church.
