It is common to write, "Jesus' disciples."
In general, you make a noun (common or proper) possessive by adding apostrophe and 's':
Mark's desk is near the teacher's desk.
The same applies to common nouns ending with 's'"
This is the boss's office.
When a proper name ends with 's,' usage is divided. Some people prefer apostrophe + s in all cases:
Charles's tie, Jesus's beard, Achilles's heel.
Other people would add only apostrophe in all these cases.
Yet other people would make a distinction with Biblical or classical names:
Charles's tie, Jesus' beard, Achilles' heel.
There are two accepted forms for possessive singular nouns that end with an s:
Add an apostrophe (') after the existing s at the end of the word: Jesus'
Add an apostrophe s ('s) after the existing s at the end of the word: Jesus's
Examples:
