Outward holiness, or external holiness, is a Wesleyan–Arminian doctrine emphasizing modest dress and sober speech. It is a testimony of a Christian believer's regeneration, done in obedience to God. The doctrine is prevalent among denominations emerging during the revival movements, including the Pietist Lutherans and Methodists (especially those in the Holiness Movement), as well as Pentecostals. It is taken from 1 Peter 1:15: "He which hath called you is Holy, so be ye holy in all manner of conversation."
