Sorry - that's what happens with jargon - Jesus' "church" is the body of believers if you notice it's singular. This body has two tenants Mt 22:36 "You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the great and first commandment. And a second is like it, You shall love your neighbor as yourself. On these two commandments depend all the law and the prophets.” and this is were the man made "church" comes into play. We (I am as guilty as anyone) like to "customize" this which leads to the plethora of man made "churches".
