restorationist (n.)

1788, "one who believes in the final restoration of all to God's favor after temporary punishment of the impenitent," from restoration + -ist. Related: Restorationism. Regarded from without as a form of universalism but a subject of contention in the sect 1820s-30s. As "one who restores dilapidated buildings," by 1877 (implied, perhaps, in anti-restorationist; at any rate, restorationist is by 1880).
