Rev 3:13He that hath an ear, let him hear what the Spirit saith unto the churches. 

Are there many churches or just one Church? This verse gives us a clue to the question in the picture. The clue is in plurality as the letters are to 7 churches mentioned in the book of Revelation. So what is the Church and is there only one Church? In today’s world of Churches, we find that there are literally thousands of churches and some going so far as to say that they are the one true church. Wikipedia estimates that there are 41,000 different denominations and probably as many if not more para church groups. Para church groups are organisations that name the name of Jesus but follow their own activities other than church activities like conducting services. They range from help groups to donors of things and money to needy people. Someone like Compassion or World Vision can be considered as a para church group.
