Wouldn't the fact that they don't properly administer the sacraments mean that they aren't a true church?
Larry, I still consider a Presbyterian church a true church even though they don't properly administer the sacraments.
Actually, most Presbyterians I know consider Baptists to be in error regarding baptism, but they don't deny we're a true church. That arguments cuts both ways.
I know that in our denomination (URCNA) there are some people and leaders who don't believe that baptists are saved - perhaps because of the counter-reformation - who knows. As far as I'm concerned, anyone who doesn't believe that Spurgeon, Gill and Pink were saved needs a lot more than his head examined.

These people need to be reminded that it was paedos who murdered baptists, not the other way around.
I would rather sit under strong meaty preaching from a reformed baptist than sermonettes for Christianettes preached by many Presbyterians any day. I'm not saying all presbyterian preachers preach that way, but I do tend to favor more baptist preachers than Presbyterians.
As far as baptism goes, A baptist brother of ours said he'd rather see an infant be baptized and grow up to accept the promises of the covenant and live a godly life than see a young man get baptized and live like the Devil. Likewise, I'd rather see a young person get baptized upon making a profession of faith and live in a godly manner than see a young child who's been baptized in infancy take his baptism for granted.
