The legislative and social effects resulting from the temperance movement peaked in the early 20th century and began to decline afterward. The effects on church practice were primarily a phenomenon in American Protestantism and to a lesser extent in the British Isles, the Nordic countries, and a few other places. The practice of the Protestant churches were slower to revert, and some bodies, though now rejecting their formerly prohibitionist platform, still retain vestiges of it such as using grape juice alone or beside wine in the Lord's supper.
