This is relatively straightforward; I suspect it's the word order you find
confusing: (1) AUTOUS is the object of the complEmentary infinitive
EPIKALEISQAI; (2) the first QEOS is, of course, the subject of OUK
EPAISXUNETAI; the second construes with AUTWN ("god of them, their god")
and the phrase QEOS AUTWN functions as the predicate nominative with the
passive infinitive APIKALEISQAI--verbs like "call," "elect," "appoint,"
etc. take predicate accusative when the verb is active, predicate
nominative when the verb is passive.
