Thank you to Brother Don Nesbitt his youtube handle is @w46try7. the Lord's bloodhound. He is one of the reasons, this article exists.

If you look at my profile, you will see I wrote a study of Diodorus of Tarsus's soteriology, and you will see in it, I made the argument that he is very close to John Wesley. This is true.

The problem is that John Wesley can sound like a theosis believer if you aren't listening.

Deification is the (not true) doctrine that salvation is a life-long process, and you aren't immediately saved.

John Wesley believed you are saved immediately but you can lose it.

“30. The Sum of all is this. If the Scriptures are true, those who are holy or righteous in the Judgment of GOD himself: Those who are indued with the Faith that purifies the Heart, that produces a good Conscience: Those who are grafted into the good Olive-tree, the Spiritual, invisible Church: Those who are Branches of the true Vine, of whom CHRIST says, I am the Vine, ye are the Branches: Those who so effectually know CHRIST, as by that Knowledge to have escaped the Pollutions of the World: Those who see the Light of the Glory of GOD, in the Face of JESUS CHRIST, and who have been made Partakers of the HOLY GHOST, of the Witness and of the Fruits of the Spirit: Those who live by Faith in the Son of GOD: Those who are sanctified by the Blood of the Covenant; may nevertheless so fall from GOD, as to perish everlastingly.

Therefore, let him that standeth, take heed lest he fall.” - John Wesley, “Serious Thoughts Upon the Perseverance of the Saints”

Diodorus of Tarsus taught that salvation was freely given.

“Necessarily he set forth ‘those who call upon him.’ For God does not give grace without discernment, extending it even to those who are unwilling to offer so much to the Benefactor as at least to ask and pray with him. And lest anyone say that many fail to call upon the Lord Jesus out of ignorance rather than unbelief and ingratitude, he shows through what follows that God took away even the excuse of their ignorance, sending evangelists and heralds who urge and invite them to ask for the gift. Therefore he added what follows.” - Diodorus of Tarsus/Diodore of Tarsus, Romans 10:11-13.

He taught salvation could be lost.

“Fulfill, he says, the work of love, knowing the time is urgent and demands virtue. For those previously ignorant of the truth and living in the darkness and night of error were reasonably, like those sleeping, in a state of inactivity regarding good works. But those now, since they have been enlightened by the memory of the Savior and have come to be in the day, owe it to rise from the idleness of sleep and take hold of good works. “For now our salvation is nearer than when we believed,” that is, when we knew the more profitable of works, it has become easier for us to be saved than when we were being instructed in the word of faith. For at the same time as believing in Christ, we did not also have an accurate comprehension of what should be done, nor was it manifest to us from which actions to abstain, and which to pursue.” - Diodorus of Tarsus/Diodore of Tarsus, Romans 13:11

That's John Wesley's school of thought.

I believe in OSAS, no way for Christ to amputate.

John 10:28

“And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.”
