Aaqil Ahmed, BBC head of religion and ethics, has recommended in the report that the British public service broadcaster must diversify its religious programmes.
"Christianity remains the cornerstone of our output and there are more hours dedicated to it than there are to other faiths," Ahmed said in a statement.
"Our output in this area is not static, though. It has evolved over the years and we regularly assess it," he added.
BBC director-general Tony Hall is considering the review's findings, which said the broadcaster's current output was "too Christian" and recommend more Hindu, Sikh and Muslim religious programmes be added to the mix, The Sunday Times reported.

The debate follows a government white paper last week on the BBC, which will require it to serve ethnic minorities better.
A BBC spokesperson said, "we are actually intending to do more programming around Christianity and more on other faiths as well, so there is absolutely no question of an 'either or' on our output."
BBC's religious output currently includes 'Songs of Praise' and 'Sunday Morning Live' on television, plus 'Thought for the Day' and 'Act of Worship' on radio.
The Muslim Council of Britain suggests televising Friday prayers from a mosque would be one way to better serve Muslim viewers, but not at the cost of Christian programmes.
