​Self-acceptance is recognized in diverse schools of Christian and Eastern theology as well as in various schools of counseling and psychotherapy (e.g., Humanistic, Rational-Emotive Behavior Therapy, Cognitive Behavior Therapy, Acceptance Commitment Therapy) as a major contributor to mental health, life satisfaction and wellness. A review of the professional literature reveals there is no text that spells out how different theologies, theories of personality and approaches to counseling and therapy conceptualize self-acceptance and how this concept is interrelated toother aspects and constructs of spirituality and psychological functioning(e.g., flexibility, mindfulness). Additionally, the field of positivepsychology, which studies the character strengths and virtues that helpindividuals to experience well-being and to flourish, has largely ignored theconcept of self-acceptance.
