Clement of Rome is one of the earliest Church Fathers, student of, perhaps, Peter. His writings sound Open-Theistic. His idea is that God actively watches the world and sees everything we are doing. This is not a “timeless” knowledge, but an active scanning. God is “receiving” information, which Calvinists claim God cannot do. We also have Clement encouraging people to reform their ways to avoid judgement. The future is not set, but open.

1Clem 27:5
Who shall say unto Him, What hast thou done? or who shall resist
the might of His strength? When He listeth, and as He listeth, He
will do all things; and nothing shall pass away of those things that
He hath decreed.
1Clem 27:6
All things are in His sight, and nothing escapeth His counsel,
1Clem 27:7
seeing that The heavens declare the glory of God, and the firmament
proclaimeth His handiwork. Day uttereth word unto day, and night
proclaimeth knowledge unto night; and there are neither words nor
speeches, whose voices are not heard.
1Clem 28:1
Since therefore all things are seen and heard, let us fear Him and
forsake the abominable lusts of evil works, that we maybe shielded by
His mercy from the coming judgments.
1Clem 28:2
For where can any of us escape from His strong hand? And what world
will receive any of them that desert from His service?
