〜(ら)れる - Ambiguity between passive and Keigo

Question

In my Japanese Bible, it often uses the 〜(ら)れる Keigo form when talking about God's actions. However, there are certain cases when talking about both people and God in the same sentence where the use of 〜(ら)れる is ambiguous as to whether it's the Keigo for God's actions, or the passive of what will happen to the people.

Take this verse:

あなたが叫【さけ】べば「わたしはここにいる」と言われる。ー　イザヤ書 58:9
When you call to me, I will respond. - Isaiah 58:9

So I'm confused as to whether this is shortened from

あなたが叫べば（あなたが）「わたしはここにいる」と言われる　→　If you call, you will be told "I am here"

or

あなたが叫べば（神様【かみさま】が）「わたしはここにいる」と言われる　→　If you call, God will say "I am here"

Are there any indicators as to which it might be? Does it even matter?

Answer 1

I agree with sawa that from syntactic clues this fragment is ambiguous, but there are actually more syntactic clues if you look at the whole sentence, which is:

あなたが呼べば主は答え、あなたが叫べば「わたしはここにいる」と言われる。

It would be possible, but quite perverse (and impious, as Sawa notes!) to interpret the 言われる in the second half as a passive rather than an honorific form parallel to 主は答え. Note that you can see the same construction, right down to the subject-dropping, in the Vulgate version, where "dicet" ("(He) will say") is parallel to "Dominus exaudiet" ("The Lord will hear"):

tunc invocabis et Dominus exaudiet clamabis et dicet ecce adsum

Answer 2

Just from syntactic clues, this sentence is ambiguous. Taking into consideration that this is from the bible, it is very likely that the usage here is subject honorification. If it were passive, then it would slightly entail that あなた (or you) is bothered by the God by being said that he is here. That would be an impolite thing to write for a God.
