Here’s a summary of the PowerPoint slides:

Calvinism is critiqued for imposing a philosophy on Scripture, relying heavily on Augustine and altering scriptural meanings to fit its doctrines rather than Scripture itself 1 2

- Perseverance Doctrine: The Calvinistic 'Perseverance of the Saints' emphasizes believer's faithfulness to the end but is argued to cause uncertainty and lacks biblical support for final salvation assurance 3 4 5

- Biblical Examples: Scripture provides examples of non-persevering saints in both Old and New Testaments, challenging the Calvinistic perseverance view 6 7 8

- Assurance of Salvation: True assurance of salvation is presented as a privilege for all believers based on God's testimony, not on works or perseverance, contrasting with Calvinistic doubt 9 10 11
