Maam, you forgot the first half of that Scripture.
"{YOU} work out your own salvation with fear and trembling,..."
Twising Scriptures around will not bring you to God's Will.

Yes. We're instructed to remain aware of our total dependence on Christ who has determined our salvation and delivered us from eternal death by His sacrifice alone.
The verse you site refers to our progressive sanctification -- we persevere by His work in us, ever mindful of the alternative. Humility (and fear and trembling) come from knowing our redemption depends not on our good works (of which we have none) or any implementation of earthly requirements, but on the accomplished work of Christ risen from the cross.
All of which puts a church hierarchy at a real disadvantage. Because we're not supposed to fear the church or the priest or the pastor or any loss of sacramental availability. We are supposed to singularly fear the God who gives life and who takes life, at His discretion alone.
You, OTOH, completely disregard the clear meaning of Phil. 2:13. And after all this time on this thread, I'm now aware you guys do this repeatedly. When offered Scripture which denies your position, you simply ignore it and go on to something else.
As God wills.
"For it is God which worketh in you both to will and to do of his good pleasure." -- Philippians 2:13
Seems clear to me. All of Him; none of me; and certainly none of any magisterial accomplishment.
