Plan A & Plan B
The Greek word 'katabole' is translated foundation
and with 'cosmos' is translated 'foundation of the world'.
In the New Testament there are 10 occurances of
'foundation of the world'. There are two conditions:
pro (before)
apo (since or from)
Seven start with 'apo'
Three start with 'pro'
The differences are doctrinaly significant:
the three starting with 'pro' has to do with
God's love of Christ, God's selection of Christ,
and Christ's selection of we Christ-ones.

In general:
apo (since, from) the foundation refers to Yisrael
pro (before) the foundation refers to the largely Gentile Church
of the Church Age (also: Times of the Gentiles, Age of
the Gentiles, Age of Grace, etc).
God's plan for Jesus saving the Gentiles was made
before the world; God's plan for National Israel
was made after the world was made.
