I do recognize she was in hot water with abortion proponents and the gay mafia for her opposition to them. If the preacher and his wife were helping to stiffen Giffords' spine on such things, I would applaud that.
Indeed, I was wrong to imply a church of Christ preacher couldn't find some common ground with Giffords. It's not very hard to imagine, now that I've read some of her positions. Generally working within the party religion that so steadfastly supports abortion and homosexual marriage would be sufficient to avoid such politicians, but that would reasonably become personal prerogative in the case of blue dog democrat positions, if held firmly, unlike some Democrat squeeky wheels looking to be greased.
Certainly showing the love to sacrifice one's own life for another is one of the highest virtues one can ever display (1 Jn 3:16, Jn 15:13, Mk 10:45, Lk 17:33, Jn 13:37).

While there is a similarity in the name, the church of Christ has a completely separate history from those other churches. There is no branch that connects them with the UCC, one never splintered off from the other because they were never together in any way.
Trinity United Church of Christ is just one local congregation that is under the United Church of Christ (UCC) umbrella, under their hierarchy. Disciples of Christ has a different origin, but I think I read somewhere that they are sort of merging with the UCC denomination -- could be wrong on that.
The many congregations of the churches of Christ are all completely autonomous from one another, there is no earthly hierarchy above the individual congregation.
