Albert Ellis (1913–2007) was an American psychologist who created Rational Emotive Behaviour Therapy (REBT), a major foundation for modern Cognitive-Behavioural Therapy (CBT).

Ellis understood motivation and psychopathology within a fundamentally cognitive and philosophical framework. Human beings are naturally goal-directed and seek such ends as love, approval, competence, comfort, and happiness, but psychological disturbance arises not simply because these goals are strong, nor primarily because of adverse external events, but because people transform legitimate preferences into rigid, absolutistic demands (“I must,” “others must,” or “life must”) and then evaluate themselves, other people, and circumstances according to those demands.

Thus, in the ABC formulation of Rational Emotive Behaviour Therapy (REBT), an activating event (A) does not directly produce an emotional consequence (C), because beliefs (B) about the event mediate the response, and psychopathology is maintained when irrational beliefs generate unhealthy emotions, self-defeating behaviour, low frustration tolerance, and compulsive attempts to secure approval or avoid discomfort (Ellis, 1958, 1962, 1991). Ellis’s thinking was especially indebted to the Stoic philosopher Epictetus (c. 55–135 CE), whose distinction between events and our judgments about them became a central philosophical antecedent of REBT. He was also influenced by psychoanalytic thinkers such as Sigmund Freud and Alfred Adler, although he increasingly rejected psychoanalysis as insufficiently direct and developed his own rational psychotherapy in the 1950s (Dryden, 2015; Mantzanas, 2020).

Importantly, Ellis did not regard rational insight alone as sufficient motivation for therapeutic change. Lasting change requires emotional commitment, active disputation of irrational beliefs, practice, and behaviour, so motivation is both shaped by beliefs and strengthened through purposeful action (Ellis & Joffe Ellis, 2019).

From a Christian perspective, this offers significant points of contact but also important theological differences. Ellis was an atheist and strongly critical of dogmatic religiosity, although in later work he acknowledged that REBT could be compatible with some forms of religious faith and could be used effectively with devout believers (Ellis, 2000; Nielsen & Ellis, 1994). A Christian appropriation of REBT might affirm its insistence that distorted beliefs can intensify suffering, its challenge to perfectionistic “musts,” and its emphasis on changing one’s patterns of thought, ideas that resonate with Paul’s exhortation to be “transformed by the renewing of your mind” (Romans 12:2), to “take every thought captive” (2 Corinthians 10:5), and to cultivate what is true, honourable, just, pure, lovely, and commendable (Philippians 4:8). It could also reinterpret Ellis’s unconditional self-acceptance through the theological category of grace, in which human worth rests not on achievement, approval, or flawless performance but on God’s gracious acceptance in Christ (Ephesians 2:8–10; Romans 5:8), while retaining the Biblical distinction between accepting oneself as a fallible creature and approving sinful conduct (cf. Romans 7:15–25).

At the same time, Christianity cannot simply equate “rationality” with psychological health, because Christian theology locates human transformation not merely in autonomous rational self-correction but in relationship with God, the work of the Holy Spirit, repentance, faith, grace, and conformity to Christ (Romans 8:5–14; Galatians 5:22–23). Consequently, REBT can provide a useful psychological account of how irrational evaluations contribute to psychopathology, while a Christian framework supplies a more explicitly theological account of ultimate identity, motivation, morality, suffering, redemption, and the good life. Christian adaptations of REBT have accordingly argued that Biblical beliefs themselves can be employed to challenge irrational demands (for example, replacing “I must be perfect to be acceptable” with the gospel conviction that acceptance is grounded in God’s grace) while recognising that Ellis’s naturalistic anthropology and rejection of traditional theism remain substantially different from historic Christian doctrine (Phillips, 2017; Johnson, 2021).

Ellis’s development of Rational Emotive Behaviour Therapy (REBT) offers a particularly useful psychological framework for understanding personal life strategies: the cognitive and behavioural plans through which individuals interpret circumstances, manage perceived threats, pursue opportunities, and regulate their responses to life. Beginning with his rational-emotive approach in 1955 and formalised in Reason and Emotion in Psychotherapy (1962), Ellis argued, as we have seen, that people are not emotionally disturbed simply by events themselves (A, the activating event), but by the beliefs and evaluations they bring to those events (B), which generate emotional and behavioural consequences (C). Later formulations added disputing irrational beliefs (D) and developing more effective rational beliefs and behaviours (E) (Ellis, 1962, 1991, 1994).

This is directly relevant to the concept of life strategies because it suggests that successful navigation of life depends partly upon learning to distinguish what can be controlled from what cannot, challenging rigid demands such as “I must succeed,” “others must treat me fairly,” or “life must unfold as I want,” tolerating frustration and uncertainty, and replacing catastrophic or self-condemning evaluations with flexible preferences, problem-solving, persistence, and unconditional self-, other-, and life-acceptance (Ellis & Joffe Ellis, 2019). In this sense, Ellis teaches that a resilient life strategy is not merely the avoidance of threats but a disciplined method of appraising circumstances, regulating emotion, choosing constructive action, learning from consequences, and pursuing valued goals despite adversity.

Ellis’s emphasis on rationally examining beliefs is valuable but requires theological qualification. Christianity similarly teaches intentional transformation of the mind (“be transformed by the renewing of your mind” Romans 12:2) and calls believers to attend deliberately to what is “true,” “honourable,” “just,” “pure,” and “praiseworthy” (Philippians 4:8), while exercising discernment, self-control, perseverance, and wise action. Yet a Christian life strategy is not ultimately founded upon autonomous human rationality or self-sufficiency, but upon faith in God, dependence upon divine grace, obedience to Christ, and the hope of providentially guided transformation (2 Corinthians 10:5; Galatians 5:22–23; James 1:2–5).

Thus, Ellis can illuminate how people may challenge destructive interpretations and cultivate adaptive responses, while Christian theology adds the deeper question of what constitutes truth, virtue, purpose, and the good life. Rather than simply disputing thoughts because they are psychologically unhelpful, the Christian seeks to bring thought and conduct into conformity with God’s revealed truth and character (Romans 12:2; Ephesians 4:22–24), making Ellis’s cognitive-behavioural insights potentially complementary to, but not a substitute for, Christian anthropology, discipleship, prayer, Scripture, community, and reliance on God.
