You need to work on your perception of what constitutes the Christian faith, I think your lack of a holistic understading of the faith is quite stunning.
There is a reason catechumens were teached the faith prior to their baptism in the early church and still does so in the Catholic Church as well as the Orthodox Church.
Ethics cannot be separated from a life in Christ. There is one faith, one Lord and creed. The faith is metaphysical and should be the cornerstone of any believers actions and life as a whole. It cannot be fractured as to only apply to parts of our lives.
It a package deal.
First, no need for the personal attacks.
Second, I am not saying anything different to what you're saying. The early church often had a catechumenate of several years; so why is it so extraordinary that I'm saying people might not have everything sorted on day one now? People take time to grow.
Out of curiosity, how does Luke 14:27-33 fit in? How do you set people's expectations for what they will need to give up and take up in order to follow Jesus?
We offer God our whole selves and our whole lives; but none of us knows, when we begin, what that will look like. I certainly didn't!
I'm responsible for everyone that I meet, as should any person claiming Christian faith.
I disagree; or at least, I'm not responsible for the random atheist in the street in the same way as I'm responsible for someone who places him or herself under my ministry.
If someone says, "such and such isn't a sin", but it is, I have a responsibility to correct them. If someone says, "I know that this is a sin, but I'm struggling with it", I offer them my support. You gave off the impression that you didn't desire to tell people that they're in sin (appealing to, they've already heard...), so I offered correction there as well.
We're talking in the abstract about pastoral decisions which need to be made for real people. On the whole, in real life, I have found that I don't need to tell gay people about sexual sin; they know all too well. For them the pastoral focus often needs to be on offering hope.
I'm not saying that someone has to have everything sorted out right away, because I still have my own struggles and know that it's not realistic. You seemed to suggest that you would rather avoid the issue altogether, leaving it alone and letting that person sort it out on their own whenever they "get around to it", and I saw it as problematic.
I have found, on the whole, as a gross generalisation, that this is not an issue I need to focus on. That's not the same as letting someone sort it out on their own if they want or need help. But - for example - I have a young gay man who's asked to come and see me next week. From the conversation we've had I expect he'll ask me to hear his confession. I rather suspect that if the first time I'd met him, I'd lectured him about the evils of his sex life, he wouldn't now trust me enough to approach me for that conversation; but because I've interacted with him in a way which puts hope before condemnation, now that conversation is possible.
And that's where the possibility of God's grace comes in! So I am very anxious not to push people away, but rather to interact with them in a way which is hospitable and which always leaves room for God to be at work.
