This post sounds to me like the ones in Corinthians who said THEY were not of Paul or Apollos but of JESUS! They were just as wicked as the others except they were pompous and holier than thou too.
No one is exalting Calvin above God. There's not a word in any one of these posts that even slightly indicate such a thing.
Do you thank the troops for your freedom?
Do you celebrate Memorial Day?
If so, then you are as guilty of what you accuse as those you accuse.
The fact of the matter is that it is perfectly reasonable to thank people for what you have. Troops, George Washington and John Calvin are among those that you OUGHT to thank.
God does not look kindly on holier than thou attitudes which turn men into ingrates.
God gets all the glory for everything but his Word teaches us to be grateful for others he uses to contribute to what we have as well.
Could you give us some scripture that supports what you have said?
