Paragraph 23.3
Of the Second London Baptist Confession of Faith
Whosoever taketh an oath warranted by the Word of God, ought duly to consider the weightiness of so solemn an act, and therein to avouch nothing but what he knoweth to be truth; for that by rash, false, and vain oaths, the Lord is provoked, and for them this land mourns.1
The Westminster Confession of Faith (1646)
22.3
Whosoever taketh an oath ought duly to consider the weightiness of so solemn an act, and therein to avouch nothing but what he is fully persuaded is the truth.1 Neither may any man bind himself by oath to anything but what is good and just, and what he believeth so to be, and what he is able and resolved to perform.2 Yet it is a sin to refuse an oath touching anything that is good and just, being imposed by lawful authority.3
