Justification from eternity

Justification from eternity is not part of mainstream Protestant theology, and is explicitly rejected by the Westminster Confession of Faith, which asserts,

God did, from all eternity, decree to justify all the elect, and Christ did, in the fullness of time, die for their sins, and rise again for their justification: nevertheless, they are not justified, until the Holy Spirit does, in due time, actually apply Christ unto them.

[1]Reformed orthodox theologians taught that justification is part of an order of salvation, and that it follows effectual calling and a person actually believing.

[2] Francis Turretin in his Institutes of Elenctic Theology speaks of some who teach instead that justification was actually executed eternally.

He agrees that justification was decreed eternally, but counters that actual execution occurs during people's lives.
