I first came across this in the history of Byzantium podcast.
This isn't exactly Jihad levels yet but with warring against Muslims to conquer or reconquer lands on an ecclesiastical basis already developing in the West, a Nikephorus successful in making fallen soldiers against the Muslims martyrs then adopting crusader ideas developing in the east like absolution of sins and a duty to conquer lands from Muslims will get us about there.
I guess the main side effect of this would be a possible development of an Orthodox equivalent to the "Ghazis", foreign Christian soldiers coming to serve under Rome for the religious duty and religious benefits of fighting the Muslims.
Now, given that of course there'll also be secular advantages in Roman pay, we could get something like the Varangian guard develop except instead of as Imperial bodyguards, they'll be more like shock troops. In how they originate at least and it could be a way of the Orthodox converting peoples without even being aware of it.
Like, some Kievian Varangians or Polovtsy go on an Orthodox Jihad, comes back with alot of money his cousins in the Scandenavia or Kazakhstan hear of it and arrive in Constantinople and are required to do some Christian stuff to join and are told they're rich and winning due to this religion.
Nikephoros also disagreed with the church on theological grounds. He wished the church to elevate those soldiers who died in battle against the Saracens to the positions of martyrs in the church – similar to the status of "Shahid" which the Emperor's Muslim foes bestowed on their own fallen soldiers. In the Christian context, this was a highly controversial and unpopular demand
