My first response to this was “Nope.” Then the Father started talking to me.
Mt 11:19 The Son of man came eating and drinking, and they say, Behold a man gluttonous, and a winebibber, a friend of publicans and sinners.
Mr 2:16 And when the scribes and Pharisees saw him eat with publicans and sinners…
Okay, so most of the Christian world would consider being gay or a homosexual a sin, Selah. (Stop and think about it considering the above verses) Since when are we called to live our lives in the monastery of seclusion? Is going to a family wedding of an unbelieving family member any different than going to a wedding of a lgt (lesbian, gay or transexual)? Are they both sinners? Yes! Or are you afraid to go, because you would slip over and become lgt? Who will be the light at such events? Did Jesus draw the line to eat with liars, but the prostitutes were left on the outside? Sin is sin. (and yes, there are varying consequences to sin, in this world and also on judgment day, but an unrepentant liar will be kept from eternal life as well as an unrepentant murderer). Here is another verse similar to the above ones, but with a twist.
Lu 15:2 And the Pharisees and scribes murmured, saying, This man receives sinners and eats with them.
The word receives means awaits, accepts, allows. You could say, He made purposely made and sought out appointments to eat with sinners. We are called to be the light wherever we are, whether it’s at communion time or eating with the “worst” sinner.
Lu 11:33 No man, when he hath lighted a candle, puts it in a secret place, neither under a bushel, but on a candlestick, that they which come in may see the light.
Darkness exists because the light (or maybe I should write the Light) is ABSENT! You are called to be an ambassador (a Light-bearer). As a Christian, could hiding your light be a sin? You may be striving for your constitutional right not to serve at a wedding and at the same time ignoring your ambassadorial duties to serve. Where is your light shining? Is it only by others that live with you under your bushel or by all because it is on your candlestick?
