The word `fundamentalism' originated in the USA following the appearance of 12 booklets (1910-1915) with the title `The Fundamentals: A Testimony to the Truth'. The purpose of the project was to arrest the challenge of the sweeping influence of modern higher criticism of the Bible and new scientific theories such as evolution. The word `fundamental' can be positive pointing out the Christian fundamentals of holist liberation of the whole person and humanity, and the values of justice, love and reconciliation. But, some popular preachers and sects indiscriminately opposed critical thinking and promoted literalist interpretation of their favorite verses with a focus on blessing as prosperous life here and hereafter. Later this trend developed into militancy and bigotry. Indian Christianity has been dangerously infected by fundamentalism which distorts Christian life and witness. With a view to educate the Christians, the Association of Theological Teachers in India (ATTI), in consultation with a group of theological college principals, has produced extensive Bible-based Guidelines in the present work.
