Who cares?
Refute them, if you can. That would be interesting. Your personal opinions bore me.
Jesus not only had the authority to do so but paying careful attention will reveal that He did so in accordance with the law. Conviction under the law required the testimony of two or three witnesses. When the witnesses all left, a legal conviction was no longer possible.
Also, the point of their wanting to have the adulteress executed wasn't about criminal justice it was about getting Jesus in trouble with the Roman authorities who did not allow the Jews (or anyone else) to execute criminals without their express permission. Jesus manipulated the situation so as to both overcome His enemies and preserve His law.
You're a veritable fount of Christian cliche.
You don't even try to do this.
Do you circumcise your male children on the eighth day of their life as Jesus was? NO!
Do you observe the dietary laws as Jesus did? NO!
Do you observe the Sabbath days as Jesus did? NO!
Do you even know what all the Sabbath days are? NO!
Jesus was a Jew, born under the law and He submitted Himself to the law and followed it PERFECTLY. A practice that you not only do not follow but wouldn't have any idea how to follow precisely because you have not been taught to live "a life like Christ".
He also brought hatred, offense and condemnation. If you think otherwise then you don't know Christ and you need to get away from whoever it is teaching you the bible because they're either just as ignorant of the bible as you are, or they're lying to you.
If more people like you than hate you, you're doing something very wrong. The truth is unavoidably offensive.
No, you haven't. Stop lying.
The single most effective ministries (I'm thinking of two in particular) I've ever even heard of, never mind actually been involved with, have had hundreds (probably thousands, actually) come to Christ precisely because of their aggressive condemnation of sinners.
God isn't the least bit interested in having homos become Christians! If they stop being a homo then, sure! By all means! But if you think that a homo can continuing being a pervert while being a follower of Christ then you're so completely ignorant of who Christ is that it calls your own salvation into question. If that's what you've been taught, then that's not Christianity, neither in doctrine nor in practice.
Christianity is about convicting people of their sin in hopes that they will repent and ask God for His forgiveness, not accepting people as they are and hoping that they'll like us enough to want to join our Sunday morning social club meetings. People are not going to get saved unless they know they need saving. Without Christ, people are going to go to Hell because they deserve it and certain people have done things that mean they deserve to die and go straight to Hell right now (e.g. murders, rapists, adulterers, child molester, Sodomites, etc) and you are NOT going to communicate that message without offending for more people than not. Nearly EVERYONE is going to be offended by that message. Those that aren't will be the rare exception. These are those that God is looking for, not the proud pervert.
