Hey @Pr. Jae -- You and I are not going to get anywhere on this one. I see that welcoming someone means embracing them and who they love. You do not...you say that you can welcome someone, but deny their love.
I will just say, should you do that to me, I would tell you where exactly you could stick your so-called welcome. I would stand with whom I loved. I would try to be gracious in your presence; however, I would be clear that if you wished to spend time with me, then my partner was part of that visitation. I would hope my mother understand the importance of inclusion and welcomed both of us into her house. If the people there chose not to be gracious to my partner, then, I would expect them to vacate my mother's house......or work it out with my mother.
I would NOT drop my partner due to what I perceived as out-dated and unfair lack of acceptance of my partner. My partner's inclusion would override my requirement to spend time with my brother who could not find the way to find Christian love and grace in our meeting.
Oops, natural reaction ... so different than man-made laws ... gods laws of nature bend with gravity ... even de lights ... read up on gravid lens!
