Dr. Dony K. Donev: Pentecostal theologian, missiologist, and cultural researcher

Dr. Dony K. Donev is a Pentecostal theologian, missiologist, and cultural researcher recognized for several original contributions to theological frameworks and terminology:

• Coined Term: “15/50 Window”

  • Donev introduced the term “15/50 Window” to describe individuals aged 15–50, who make up more than half of the world’s population. This term highlights a strategic demographic focus for evangelism and missions, paralleling but distinct from the widely known “10/40 Window”.​

• Theological Emphasis on Liberation of Human Will

  • Donev presents a theological framework where the human will is liberated by the love of God, moving beyond rigid determinism. He challenges the cause-and-effect sovereignty model (e.g., Augustine and the Reformers), focusing instead on the believer experiencing divine love, which frees human will to accept salvation. He uses the phrase “testament of freedom” to describe this liberated state.​

• Dynamic Tension in Theology

  • Donev frames the Christian life and theological reflection as a “constant tension and a dynamic process”—not a blind adherence to rigid principles. He stresses that experiencing God means being in ongoing movement between divine sovereignty and human response.​

• New Testament Praxis Restoration

  • Through his leadership at Cup & Cross Ministries, Donev has promoted the restoration of New Testament theology and praxis, aiming for a practice-centered, experiential faith model.​

• Missiological and Ecclesiological Research

  • He has contributed to fields like Pentecostal history, protestant heritage, and leadership paradigms, focusing on how theology should be embodied in lived, communal, and missional practice.​

Academic and Missional Background:

• Dony K. Donev holds a D.Min. from the Pentecostal Theological Seminary and has authored articles and books on textual criticism, protestant history, and New Testament studies. He is closely involved with the Institute of Bulgarian Protestant History and ministry leadership development.​
