Matthew 6

Verses 16–18 WEB Voices

Jesus completes the secret-piety triad—after alms and prayer—by reforming fasting: refuse gloomy display for human eyes; appear ordinary before people so that the Father who sees in secret is the true audience.

Matthew 6:16

16“Moreover when you fast, don’t be like the hypocrites, with sad faces. For they disfigure their faces that they may be seen by men to be fasting. Most certainly I tell you, they have received their reward.

Arminian

Fasting is assumed—“when you fast”—yet gloom and disfigured faces for an audience are rejected. The hypocrite’s reward is again applause, paid in full. Shared ground with alms and prayer: piety aimed at people empties itself before God.

The verse presses a sincere call away from spiritual theater. Grace enables self-denial without marketing it; believers are responsible not to trade fasting for reputation.

Reformed

Jesus names the motive: they disfigure their faces that fasting may be seen. Ascetic pain becomes advertising. The verdict matches verses 2 and 5—they have their reward already.

Even hard disciplines can serve the flesh. True fasting is Godward dependence, not a public credential of seriousness.

Matthew 6:17

17But you, when you fast, anoint your head and wash your face,

Arminian

Ordinary grooming reverses the hypocrite’s signal. Anointing and washing say: do not wear hunger as a badge. The discipline remains; the display dies.

This is practical holiness under assisting grace. You can learn to keep a secret between you and the Father—obedience that refuses to recruit spectators.

Reformed

Oil and clean face are not vanity; they are anti-hypocrisy. The disciple’s outward normalcy protects the inward act from becoming a stage.

Such restraint is not native pride management but fruit of a heart reoriented toward God. The Spirit forms people who can deny self without needing witnesses.

Matthew 6:18

18so that you are not seen by men to be fasting, but by your Father who is in secret; and your Father, who sees in secret, will reward you.

Arminian

Purpose clause completes the pattern: unseen by others, seen by the Father. He “who is in secret” and “who sees in secret will reward you”—the same gracious fatherly promise attached to secret giving and praying.

Arminian reading treasures both summons and promise. Grace enables secret fasting; the Father’s reward invites persevering trust without the narcotic of being noticed as spiritual.

Reformed

The Father’s omniscience is pastoral again: nothing done for Him is wasted, and nothing done for show escapes His sight. Secret fasting is covenant piety before the God who cares for His own.

The reward is certain because the Father is faithful. Quiet, Godward self-denial is held in His keeping; hypocrisy is exposed.

Key contrast Both affirm the Father who sees in secret and rewards fasting done for Him. Arminians commonly present the reward as gracious encouragement that motivates sincere, grace-enabled self-denial; Reformed readers commonly present it as covenant care toward those whose secret piety His grace has produced.

What earlier interpreters on each side wrote about Matthew 6:16–18.

Arminian Notable voices

“- Our Lord does not enjoin either fasting, alms- deeds, or prayer: all these being duties which were before fully established in the Church of God. Disfigure - By the dust and ashes which they put upon their heads, as was usual at the times of solemn humiliation.”
John Wesley · Explanatory Notes upon the New Testament (on Matt 6:16–18)

Reformed Notable voices

“He again returns to the former doctrine: for, having begun to rebuke vain ostentation in alms and prayer, he laid down, before proceeding farther, the rule for praying in a right manner. The same injunction is now given to his disciples about fasting, which he had formerly given about prayers and alms, not to be too solicitous to obtain the applause of spectators, but to have God as the witness of their actions.”
