Your congregation just spent money on pure poison. You need to make sure that these hymnals are never, never used, at least not for the liturgy or for the psalms.
Othewise, you need to swim the appropriate body of water, especially if you have kids!!!!
Look at The Episcopal Church (as it now calls itself). It will start breaking up this very year, and wlll be cut off from the Anglican Communion, the Orthodox, and the Roman Catholics. They are only sightly ahead on the curve from the ELCA, which will follow them into the same oblivion by the time of the next CWA.
Remember, in all of this, that God loves each and every Lutheran and Episcopalian. It may well be that he wants us to go back home to the Orthodox Church, so he is pulling the rug out from under us where we are!!! You in your congregation all might start by experiencing Orthodox worship for yourselves (in English) on a Sunday or two.
OK, so this might be a really dumb question, but is it true that the orthodox churches have no pews? People stand during the entire service? (Sorry if this is an ignorant question, but we studied church history this year in my homeschool group and that was one thing we learned.)
