Cold hearted, half devoted, earthly minded?

(Waterbury, "The Importance of Aiming
 at an Elevated Standard of Piety)

The cold hearted, half devoted, earthly minded
race of professing Christians are among the most
miserable beings on earth.

They make a compromise with the world, are
foremost in pleasure and in fashion, and are
undistinguished form the noisy, vain, and
trifling crowd.

Over their worldly mindedness, their niggardly
charities, and hollow professions, thousands
stumble into perdition!

They are . . . .
  a disgrace to the Christian church,
  a standing scandal upon religion,
  a grief to the pious,
  a laughing stock to the world.
