Beza, Calvin's close successor, played a key role in systematizing and clarifying Reformed doctrines, especially predestination. His strong emphasis on divine sovereignty, election, and particular atonement did influence later Reformed theology and intensified debates with Arminian thinkers—including his own student, Jacob Arminius. Beza is associated with the development of “supralapsarianism” and contributed substantially to the discussions that fueled the five points of Calvinism, but he did not invent the TULIP acronym or system.
The five points of Calvinism were articulated in direct response to the five articles of the Remonstrants (Arminians) in the early 17th century.
The Synod of Dort (1618–1619) formalized the Calvinist response into five “heads of doctrine,” which were later summarized as TULIP, notably after Beza’s time. Theodore Beza died on October 13, 1605, in Geneva, Switzerland. So he was not alive when the Synod of Dort created the TULIP acronym.
