Does Israel = Christ?

Prophecies which were about Messiah were fulfilled by the Messiah.

Prophecies which were about all nations are fulfilled in the Church of all nations.

Prophecies which were about Israel were fulfilled in Israel.

Prophecies which were about the Temple were fulfilled in the Temple.

Prophecies which were about Levitical worship were fulfilled by Levitical worship.

There was a difference between a historical event - which could be a type; and a predictive prophecy - which required an exact historical fulfilment. Not all predictive prophecies were symbols. 

God's original promise to Abraham to bless all nations (without distinction) through Christ came about through due process - to the Jews first, and then to Gentiles.

Gentile believers experienced the promised-salvation as well as Jewish believers, not instead of Jewish believers - and Jews first, followed by Gentiles next. 

Bible-prophecy was quite deliberate in its use of terms and identities, and the Apostles always adhered to those terms and identities in defending the emergence of the Church.
