Heidelberg Catechism Q100

Q. 100. Is blasphemy of God’s name by swearing and cursing really such serious sin that God is angry also with those who do not do all they can to help prevent it and forbid it?

A. Yes, indeed.  No sin is greater, no sin makes God more angry than blaspheming his name. That is why he commanded the death penalty for it.


When we blaspheme, we drag the name of God in the mud.  When we tolerate it around others, we are giving our tacit approval to their rejection of God’s authority. Such can never be the case for anyone who reveres God.  In the past, God used the force of government to implement this within his people, now we use our own life and witness to honor the Lord.  Read Exodus 22:28.


Blasphemy is so much more than simply the words we speak; it also includes the life we live.  When we sin purposefully, we degrade God’s name and call him a liar.  When we refuse to obey the Lord, we blaspheme and show by our life that God is worthless.  And God commands that even these non-verbal forms of blasphemy must be punished.  Read Numbers 15:30.


There is great danger when someone purports to speak in God’s name.  Such language as “God told me”, “The Lord says” and “The Spirit us urging” must be measured and restrained in our conversations.  Read Isaiah 36 and 37 and consider the words of the King of Assyria in 36:10 and God’s response in 37:6 and 37:23.


All false worship is a form of blasphemy and as Christians we must combat and evangelize the nations.  The preaching of the gospel message, discipling of believers and the fervent prayers of God’s people are necessary and pressing parts of our call to turn the sinner toward repentance.  When we evangelize, it is not just to share good news; it is to reverse the dangerous tide that many are surfing into God’s wrath. Read Ezekiel 20:27-28.


Read Matthew 12:31.  Many books have been written on this verse and a variety of opinions exist concerning it, but the meaning of the passage is not as obscure as many would make it.  The Spirit has one job and that is to witness to Jesus Christ, when we refuse to believe the internal witness of the Spirit of God concerning Jesus Christ or refuse to believe the conviction of sin the Spirit brings, there is no sacrifice for our unbelief that can suffice.  The very means of atonement God has made available are rejected therefore no forgiveness of sins can be given.  Let us never reject the leading and promptings of the Spirit.


But there is hope.  For Paul declares that once he was a blasphemer, but now he is saved by grace.  Everyone can turn from sin and accept Christ and when they do all of the offenses of the mouth and the body are forgiven and the power of God is given to us to live life new.  Thanks be to God.  Read 1Timothy 1:12-16.
