I recommend to you this excellent article by Brian McClain on how the church ought to respond to to unrepentant sinners, specifically, in the case of this article, homosexuals.
We are doing homosexuals a serious disservice by keeping them from the church’s proper liturgy. What they need is to be invited into a church where they will be loved, but will be expected to meet the demands of discipleship (baptism and obedience). What they are getting, instead, are churches issuing prophetic warnings against their lifestyle without any hope of healing, or churches compromising in order to pacify them.It is through worship that the church changes the world. Worship is how the army of the Lord of hosts marches forward. And its battle cry is definitely not "hate the sin, love the sinner".
Repent and be baptized.
