So - I emailed the guy... told him how I felt, and that we needed to talk straight up and figure things out... We're in quite a situation if he chooses not to go forward with this at this point in time, etc.
He replied:
Good morning, Holly and Adam...
Thank-you, Holly, for meeting with me last night and thank-you, Adam, for your e-mail this morning. I have been in much prayer over this issue of your marriage/wedding since the first meeting last December. I should have been more clear at that time of my convictions, based on Scripture, but I didn't want to squelch Adam's spiritual search.
I want you to know that I am going to go forward with officiating at the wedding. I do, however, want to continue discussions about the spiritual aspects of marriage, as this is the most important part of the marital relationship. I look forward to our pre-marriage sessions together where we will discuss a number of areas that pertain to marriage, including but not limited to the spiritual area.
Adam, I am so refreshed by your willingness to do what is necessary for the wedding day to be special for Holly. This speaks volumes to me. This is also the reason I did not come out more strongly in the beginning about my convictions because I did not want you to just "pray a prayer" for my sake. It must be something that comes from your heart. I am praying that the Lord will reveal Himself to you in a personal way so that you will understand His unconditional love for you.
I will be in touch soon to set a date to start our pre-marriage sessions.
-- So... He's going to do it... and I'm not being forced into anything... Yay!!
Thanks again everyone, for letting me rant... I appriciate all the advice/posts you all made.
