Which one of the following is not an indicator of Secularisation?

celebration of religious festivals in educational institutions 

The correct answer is option 3: celebration of religious festivals in educational institutions

Secularisation refers to the process by which religion loses its influence over various spheres of public and social life. While declining church attendance, reduced influence of religious organizations, and the rise of science and rationality are clear indicators of secularisation, the celebration of religious festivals in educational institutions reflects the continued role of religion in public life, which contradicts the idea of secularisation. In secularized societies, public institutions like schools typically aim to be neutral with regard to religion, avoiding the promotion or celebration of specific religious practices.

• Option 1: declining influence of religious organizations in public life: This is a key indicator of secularization. As societies become more secular, religious institutions often have less say in areas like law, politics, and education.

• Option 2: emergence of science and rationality: The rise of scientific thinking and rational explanations for the world often coincides with secularization. As science gains prominence, religious explanations may become less central.

• Option 4: declining rates of church attendance: A decrease in religious practice, such as attending church or other religious services, is a common indicator of secularization.
