Overall, there are some congregations (like some baptists churchs) in our country that accept to celebrate gay marriage. Some LGBT groups have specific issues with Catholic and evangelical churchs.
No. The specific link was about a evangelic priest that was asked by a lesbian couple to celebrate their wedding and denied service, based on his religious beliefs. The couple then started to use social media to try and cancel him, leading to a lot of internet debate about our supreme court decision to allow gay marriage.

this link may be slightly better.
BTW, just for context, evangelical groups in Brazil are seem as more conservative about the original beliefs. This make them one of the biggest targets when discussing religion, specially because they also have a LOT of political power.
