With a Christian population of 2.18 billion in 2012, constituting 31.59 per cent of the world population, Christianity has been able to carve for itself as the major religion of the world because of its distinct humanitarian approach cherished by Jesus Christ. This book, Christianity: Faith and Holy Days, is in two parts. Part I studies the status of Christianity among the world religions, its spiritual belief system, life of Jesus Christ, holy scriptures, teachings of Jesus, seven major denominations of Christianity, Christian marriage, and last rites. Part II deals with Christian Holy Days, i.e. Christmas, Easter, Feast of Three Kings, Good Friday, Holy Week, Lent, Maundy Thursday, Palm Sunday, Pentecost, and Shrove Tuesday. The book is illustrated with over 70 diagrams and rare photographs. The book should be useful for the students studying religion and theology in general and Christianity in particular. All those wishing to know about Christianity will also find it useful.
