This album marks the beginning of Metal Church's third major line-up, with the addition of Ronny Munroe (vocals), Jay Reynolds (guitar), and Steve Unger (bass).

Reviewer Eduardo Rivadavia of AllMusic lamented "the band's maddening tendencies for songwriting inconsistency, matching every memorable turn like 'Hero's Soul' or 'Sunless Sky' with an equally forgettable outing like 'Wings of Tomorrow' or 'Bomb to Drop.'"

He criticized new singer Ronny Munroe, who "doesn't always have the power or presence to match the surrounding onslaught", but stated his belief that longtime fans of the band would like most of the album's songs.

[2] Tony Daley of Blabbermouth.net was also critical of Munroe's performance and was not convinced by "the sound of the pre-thrash New Wave Of British Heavy Metal" the album offers and by "the pool of average ideas" that makes up the eight minute pièce de résistance "Madman's Soul".

However he conceded that if "you don't mind the odd dip in quality, then Weight of the World is a likable, if flawed, piece of work.
