TETELESTAI 1156 = 34^2: A Theo-Mathematical Proof of the Settlement of the Debt of Sin 965 + 191 = 1156 with a Single Annuity Model t = 1 and Hammurabi Interest of 19.79% and Archaeological Evidence of the Square Papyrus Receipt

This study aims to prove mathematically and archaeologically the theological meaning of the word Tetelestai in John 19:30 as the settlement of the debt of sin. Using the methods of Greek Isopsephy, Single Annuity Present Value Analysis, and Archaeological Study of Roman Tax Papyri, a closed circle was found: Opheilemata = 965 as the principal debt, plus Loipa = 191 as interest of 19.79%, which is identical to the commercial interest rate of the Code of Hammurabi (20%), producing a total bill of 1156 which is exactly equal to the value of Tetelestai = 1156. The settlement was made with a single payment model t = 1 in accordance with Hebrews 9:28. The value 1156 is also a perfect square number 34 x 34, which is proven as the physical form of the square papyrus receipt, the square Indo-Greek coin, and the square Roman wooden charge board. These results confirm Colossians 2:14 and Romans 6:23.
