Actually the pieces of the puzzle fit together very well now and clearly show the face. You guys do know that Tim is extremely Religious right. He's a devout Christian. Josh, son of Moses means savior. He would never use Jesus as that would go against using the Lord's name in vain but Josh is ok.
Look at how Tim responds to things. He implies that he will do the work of righteousness over those who have done him and his flock wrong. He considers himself a savior. He knows that I get it and that's why he's providing the rest of the roadmap.
For me honestly this whole thing is very clear to read actually. Moriarty did have to have Holmes to contend with to give his life purpose.
