My husband is Presbyterian. I am a Roman Catholic. Our son is an unbaptized babyman who we'll baptize as either as a Presbyterian or Catholic around the age most kids are confirmed. We live near several other churches and a mosque and there is a 7th Day Adventist church on our street that tries to be helpful with some of our neighborhood struggles (ie the old men on the corner who sell heroin). And we've tried to be friendly with various representatives from the church, including them in some block activities and maybe showing up at events that they hold open to the community.
One day in passing (Saturday most likely) I mentioned to a lady from the 7th Day church that my mother in law had passed away. Later that week I get an email from her asking if she and someone else from the church could stop by. So later in the week she and the pastor came by. We talked about the babyman, how great Mike's church is for families, how their church is trying to attract more families, and eventually Mike's mom. They also came with cards and gifts. The card was signed by various people in the church expressing sympathy. It was really sweet. At the conclusion of the visit the pastor led a prayer.
It was a Christian thing.
Nope not gonna nitpix about theological differences.
The body of Christ is good.
