Q556
Why does this commandment have a promise of prosperity and long life added to it?
The unique character of this commandment is noted by the blessed Apostle: “Children, obey your parents in the Lord, for this is right. ‘Honor your father and mother’ (this is the first commandment with a promise) ‘that it may be well with you, and that you may live long on the earth’” (Eph 6:1–3; see Q490, Q530).
Because God is a Father who keeps his promises, the Fifth Commandment pledges a visible reward, that his people might be all the more moved to obedience, being assured that the good order of families, and of all social life, depends upon it (cf. 2Ti 3:2, where disobedience to parents marks the perilous last days; see Q559).
