“No,.. without Christ there is no Christianity...anybody can start a Church..and do.”
No, anyone can establish a sect.
“The question is always do you practice Christianity or Churchianity? There is a gulf between the two.”
“Churchianity” is not a real thing so I couldn’t practice it even I wanted to. All “Churchianity” is really is a Protestant fantasy, a straw man really, to attack the Church with because they are not in it.
You can call churches “sects” if you want, no doubt those who are members of their churches would certainly disagree with your term...but calling them sects doesn't make them that any more than calling them a church does....because.... Christ's Church is made up of ALL those who believe in Him and His ‘finished work’ on their behalf, regardless of where they worship Him....
As believers ‘WE ARE’ that building:
.......” But you ARE a chosen people, a royal priesthood, a holy nation,.. ‘a people belonging to God’,.. that you may declare the praises of him who called you out of darkness into his wonderful light. ... Once you were not a people, but now you are the people of God;... once you had not received mercy, but now you have received mercy”....
1 Peter 2:9-10
.....” Consequently, you are no longer foreigners and aliens, but....” fellow citizens with God's people”.... and “members of God's household”, built on ‘the foundation of the apostles and prophets’, with Christ Jesus himself as the chief cornerstone......”In HIM” the ‘whole building’ is joined together and rises to become a holy temple in the Lord..... And in him you too are being built together to become a dwelling in which God lives by his Spirit.”.....
Ephesians 2:19-20
Churchianity certainly is a real thing....we have all seen many people sit in the pews week after week yet they have never been saved....they go because that is what they were raised to do but their hearts are far from Him...and this unrecognizable to them because they are going through the motions of Christianity but not of it. They can even use Christian terminology yet not have an understanding of what it means ‘to know Christ personally’.
