Simply reference the the appropriate clause of the ES specification that defines the function. EG, "the JSON.parse function defined in clause 15.12.1.2 of Ecma-262 Edition 5.1" (but the clause number is likely going to change for ES6)
Within ES5 we used a phrase like "the standard built-in JSON.parse function" to refer to the specified built-in function rather than the current value of the JSON.parse property.
Within ES6 we will use a formalism like %JSONparse% to mean the something. However, note that this notation means the built-in function as associated with a specific realm. This is important because the algorithm does realm specific things things like allocate objects and initialize their [[Prototype]] with a Realm specific value.
