Todd Friel, John Macarthur's Conference Host, Flashes 666 Hand Signals
Todd Friel
Todd Friel played the role of a group facilitator at John Macarthur's recent Strange Fire Conference (Oct.16-18, 2013) facilitating dialogues with the various conference panelists.  One can click here to see him facilitating a dialogue with John Macarthur and a few of the other Strange Fire panelists.
According to the Strange Fire website, "Todd studied to be a pastor only to discover he was not actually saved. Presently he is the host of the syndicated daily radio program 'Wretched Radio.' Todd is also the host of 'Wretched TV,' available in eighty million American households..." [Question: Do you believe Christians are allowed access to 80 million American households?]
Wretched TV
Recently Todd Friel hosted a segment of Wretched TV called "Does God help those who help themselves?" It's during this segment (posted on June 17, 2014 by wretchednetwork) that Mr. Friel can been seen flashing the 666 hand signal several times.  (I would like to note that I wouldn't make any mention of these hand signals if I believed Mr. Friel's intention was to flash the "OK" sign simply because he wanted to convey the meaning that something was alright.  The occult meaning of this "OK" signal is explained in the next section.)
The Satanic 666 Hand Signal
"Westerners know it as the 'okay' (or 'OK') sign. It's done with the fingers and thumb of right or left hands (usually the right). Simply touch the index finger to the thumb, creating a circle. The other three fingers then spiral off and there you have it—the well-known symbol for OK. Universally, this sign means alright, acceptable, good, right-on, you bet!, A-OK, satisfactory... 
"But to occultists, the OK sign takes on darker significance. First, we have the circle, indicating the sun deity and the Mason's never-ending quest for more light. To Freemasonry, the circle also represents the female genitalia, or yoni. In the Hindu religion, the OK sign is a revered mudra (sacred gesture) meaning 'infinity' or perfection. It is associated with the female genitalia — thumb and forefinger pressed together at the tips with the other three fingers extended. 
"In the practice of tantric yoga (sex rituals), the OK sign is a token of ecstasy, spiritual and physical. In ancient Sumeria and Persia, charms and amulets have been discovered of fingers and hands in the modern OK position, joined along with horns implying fertility. The three fingers extended outward are symbolic of ecstatic union with the Goddess, the third member of the pagan trinity. 
"In Satanism, when making this sign the three fingers not used to make the circle are considered symbolic of the unholy trinity — horned God, Goddess, and offspring (antichrist). Some go so far as to adopt the view that the bent three fingers are shaped as three number six's, or 666. Thus, we have 666, the sun deity (Lucifer), the Goddess (Mystery, Babylon the Great, Mother of Harlots), and the beast (antichrist, 666), all in one unitary hand sign. Oh what a web of evil wicked men can weave around something seemingly so ordinary and mundane. 
"In the Illuminist philosophy, the OK sign becomes a sign indicating approval of the Divine King, their coming Lord of Light, whom we as Christians know as antichrist. To them it means, 'He approves our undertaking.' This meaning is roughly equivalent to the words in Latin atop the all-seeing eye of Osiris on our U.S. one dollar bill—Annuit Coeptus.

Another Hand Signal?
During a one second span in this video (from 2:27-2:28), Mr. Friel goes from the 666 hand signal to the hand position as seen in the pictures below.  I don't believe it is a normal or natural hand motion to go from the "OK" sign with the thumb and index finger touching to the sign seen below with the thumb and ring finger touching and with the other three fingers pointed up.
The Serpent
Of interest, this 3 1/2 minute long video also features what appears to be a bronze-colored coiled serpent.  And, though perhaps it wasn't intentional, the serpent's body is fashioned in a way by which one can see two or more "6's" within the coils.  
One church website which also exposes the "OK" hand sign as a satanic symbol states the following regarding the circle within the "OK" sign:  
"It’s the ok sign, right? This is what it really means.
"First, we have the circle, indicating the sun deity, and to Masons, symbolizes the never-ending quest for light... It is also a Oroborous, an ancient symbol depicting a serpent eating its own tail, and is an entire article in itself, because this is used in many company logos."
