If you showed me him using it against the church I must have missed it because I sure never saw that in the scripture here is what revelations says Revelation 19:15. This verse states that a sharp sword comes out of Jesus' mouth, with which he will strike down the nations and rule them with an iron rod
Now you can believe what it says or not but while your scripture you say it says something when it doesn't mine clearly states what it says as well as the other verxses I posted clear as day we are to encourage build up and bring each other to good works but you disregard this and for whatever reason refuse to accept it as God's word.
Not to mention let us say your right and that Christ is to bering a sword against the church that is Christ not us the bible and Jesus himself says how we are to treat one another do you disregard the words of Jesus as well?
Rev.2:16
You assume I disregard the verses you quoted because I want you to see that it's not all rainbows and unicorns which is how you want to make it. Christ is equally "lover and warrior". If you want to be like Him you need to understand that.
