Christian 'art experts' seem to think so.
As their website states: "The Cathedral Church of Saint John the Divine, the Cathedral of the Episcopal Diocese of New York and the seat of its Bishop." St. John the Divine is an architectural marvel in this day and age, a cathedral constructed in medieval style with traditional stonework - worked by skilled masons... eh, eh, eh. The all inclusive community at the Cathedral openly welcomes all types of people... even gays. Cross your fingers and shout exorcism prayers as fast you can and get out of there! Just kidding - but conspiracy theorists have a ball with that place. Especially as it concerns the art and architecture - the black helicopter shaped sanctuary light, and, and, and... Okay - I made up the sanctuary light design bit - but it could happen.
John the Divine is not a Catholic church, it isn't even a part of the new ordinariate - which was more or less formed because faithful Anglicans wanted to get away from their liberal counterparts at churches such as St. John the Divine. No doubt it is a very liberal church. But as such, it remains just a protestant church, the edifice of which is constructed in the ancient manner of the great medieval Gothic and Romanesque style Cathedrals of Europe. The traditional ornamentation is executed in the traditional manner - chiseled by hand by skilled artisans. The art and symbolism is decidedly modern and reflects the locality wherein the church is situated, with all its contemporary nuance and features.
Typical of the architectural style of the old cathedrals, the entrance is surrounded by scenes of the Last Judgement, and in the article referenced here, particular scenes from the Book of Revelation are depicted in contemporary imagery: For example, scenes depicting NYC being destroyed - the World Trade Center towers visible, and so on. This has always been a perfectly acceptable way in which to express end times motifs - especially since the original intent of sculpting such images in the first place was to evangelize the illiterate of the time and place. A notion obviously lost on our highly educated and sophisticated society today.
The article, Prophetic Pillars on St. John the Divine, attempts to lay out all of the sinister symbols embedded in the art and architecture of the Cathedral and makes the claim there are occult images and 'prophecy' pointing towards the establishment of one world religion, and United Nations domination, leading to the rule of the Antichrist. For instance the author sites a Kabbalah Tree of Life symbol - something not unknown in medieval times - the Christian variety of which even Bl. Raymond Lull delved into - before or after his conversion I'm not certain. Nevertheless, it is not so unprecedented - despite the fact it is considered part of the "New Age". I'm not sure it is a covert symbol in this case however.
On another pillar photo depicting the resurrection of the dead and a labyrinth - also very ancient - the author makes this notation:
A scene depicting a birth from some kind of flower, surrounded by mummies and above a lamb with its legs tied. Who is being born? Is the Anti-Christ who is said by the Book of Revelation to the beast “coming up out of the earth; and had two horns like a lamb“? Underneath is a spiral vortex (symbolizing change of consciousness?) and people apparently praising or worshipping the figure.
Even if the stone carving depicted exactly what the author implies, how can that be construed as sinister when in fact it depicts what is written in the last book of the Bible? Which is in itself prophecy - and most suitable for an entrance to a Christian place of worship.
It is one of the more stupid articles and discussions (read the comments) on art and architecture I have ever come across since the embedded phallus on the Crucifix of San Damiano story. Except maybe for the snake on the rosary crucifix story - that was just ignorance of Scripture. (The reference goes back to the Book of Numbers 21 and corresponds to Christ's statement in the Gospel of John 3:14; "Just as Moses lifted up the Serpent in the desert, etc." Old crucifixes sometimes have a variety of symbols on them. - sometimes illustrating the moon and the sun, along with the phases of the moon.
My advice, don't be superstitious.
