The thing about the seven planets being pagan (and they think should be rejected).....is the fact that all of the sevens in the bible are due to the seven planets....they are all over it....for example....In Ezekiel,the man with the secretary's inkhorn by his side is Mercury/Hermes/Thoth....the God of Communication (and psychopomp).....the letter he puts on the foreheads of those groaning is the letter "Tau" which is the last letter of the Hebrew Alphabet....and linked to Saturn....Old father time/the Ancient of Days/the "Grim Reaper".....David is the planet Mars (the soldier/warrior) and Bathsheba is the planet Venus...the Goddess of love and desire.....and the list goes on and on.

The above is the Thoth tarot portraying Mercury/Hermes/Thoth and you can see stylus above his right hand and the writing scroll opposite....Mercury is the the God of communication.
You can also see in the card....the two snakes above his head portraying a stylized caduceus....Mercury always has a caduceus.....snakes on a pole..
The four elements earth,air,fire and water are also portrayed. (the four living creatures/The tetragrammaton)
The wand in his hand represents fire,the cup...water,the sword...air and the disks represent earth.
The creature bottom right is the Ape of Thoth.
From beginning to end....it is all astrology.
