Due to COVID-19, we have suspended our Catechism Service until further notice. In lieu of that service, we will post here a catechism sermon along with an order of service for home devotions with scripture and song keyed to each week’s lesson. You can view an archive of older lessons and sermons on our Vimeo channel.

Belgic Confession 15: Original Sin

Catechism Devotion for Sunday, July 5th

Opening Psalm and Prayer

Psalm 51:7-17 

Purge me with hyssop, and I shall be clean;
wash me, and I shall be whiter than snow.

Let me hear joy and gladness;
let the bones that you have broken rejoice.

Hide your face from my sins,
and blot out all my iniquities.

Create in me a clean heart, O God,
and renew a right spirit within me.

Cast me not away from your presence,
and take not your Holy Spirit from me.

Restore to me the joy of your salvation,
and uphold me with a willing spirit.

Then I will teach transgressors your ways,
and sinners will return to you.

Deliver me from bloodguiltiness, O God,
O God of my salvation,
and my tongue will sing aloud of your righteousness.

O Lord, open my lips,
and my mouth will declare your praise.

For you will not delight in sacrifice, or I would give it;
you will not be pleased with a burnt offering.

The sacrifices of God are a broken spirit;
a broken and contrite heart, O God, you will not despise.


Almighty and everlasting God, You are always more ready to hear than we are to pray, and to give more than we desire or deserve. Pour down upon us the abundance of Your mercy, forgiving us those things of which our conscience is convicted, and giving us those good things for which we are not worthy to ask, except through the merits and mediation of Jesus Christ, Your Son, our Lord. Amen

Psalm — “God, Be Merciful to Me” Psalm 51C


Scripture: Romans 5:12-21

Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned— for sin indeed was in the world before the law was given, but sin is not counted where there is no law. Yet death reigned from Adam to Moses, even over those whose sinning was not like the transgression of Adam, who was a type of the one who was to come.

But the free gift is not like the trespass. For if many died through one man’s trespass, much more have the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many. And the free gift is not like the result of that one man’s sin. For the judgment following one trespass brought condemnation, but the free gift following many trespasses brought justification. For if, because of one man’s trespass, death reigned through that one man, much more will those who receive the abundance of grace and the free gift of righteousness reign in life through the one man Jesus Christ.

Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men. For as by the one man’s disobedience the many were made sinners, so by the one man’s obedience the many will be made righteous. Now the law came in to increase the trespass, but where sin increased, grace abounded all the more, so that, as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord.

Confession of Faith:                Belgic Confession
Article 15: Original Sin

We believe that by the disobedience of Adam original sin has been spread through the whole human race. It is a corruption of all nature—an inherited depravity which even infects small infants in their mother’s womb, and the root which produces in man every sort of sin. 

It is therefore so vile and enormous in God’s sight that it is enough to condemn the human race, and it is not abolished or wholly uprooted even by baptism, seeing that sin constantly boils forth as though from a contaminated spring. 

Nevertheless, it is not imputed to God’s children for their condemnation but is forgiven by his grace and mercy—not to put them to sleep but so that the awareness of this corruption might often make believers groan as they long to be set free from the “body of this death.” Therefore we reject the error of the Pelagians who say that this sin is nothing else than a matter of imitation.

Lesson: “Original Sin and Forgiveness” — Mr. Luke Gossett


Praise God from whom all blessings Flow
Praise him all creatures here below
Praise him above ye heavenly hosts
Praise Father, Son, and Holy Ghost

Closing prayer — Evening Prayer

Merciful God, we come to You now at the end of this day in the name of our Savior, that Light shining in the darkness, dispelling the night of our sins and the blindness of our hearts. Lord of our labor, now be Lord of our rest. Free us of doubts, anxieties, and temptations, and continue to work Your sanctifying grace in us even as we sleep. Remembering that we are not only frail but sinful, we ask You to defend us from all dangers, but especially from the assaults of the world and the devil, as well as from the disease of our own hearts. We confess that we have not spent this day without grievously sinning against You, to whom all hearts are open and no wickedness is hidden. Yet, clothed in the righteousness of Your dear Son, we call on Your name and claim Your salvation. Give us repentant and believing hearts that delight in following Your ways. We ask also that You would be with those who are afflicted with grief, pain, temptation, doubts, and especially for [specific requests]. Together with them, preserve us all in one communion and body until we enter at last Your everlasting rest. This we ask in the name of Christ our Savior. Amen.
