Ok... after pondering this a bit more, I have this to add...
The 'Jesus' tattoo on Justin's leg is what Christian Fundies (such as myself) call "The Dying God".
In other words, it's not really Christ.
As you know Salt, Jesus is the 'Living God'. He is risen, and will always be alive for ever more.
What you are seeing in Justin's ink, is the Catholic version of Jesus, which fits the model of a god that is always dying and rising and dying and rising over and over... kind of like the Sun. Rising and setting.
It is a Solar Deity.
I got a "one minute sound byte" for you ready to roll.
Fast forward to the 2:10 mark and watch for about a minute or so to get the jist...
Last but not least, it would appear that Justin is setting up his body for Magick (with a 'K'). The opposing symbology acts like + and - ... which is important if you want to really gain power (so to speak) in this world.
Besides, if Justin was really a Christian he would know the basics...
Leviticus 19:28
"Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the LORD"
