Question & Answer 33

Q: Why is he called God's "only Son" when we also are God's children?

adopted by grace through Christ.2

Question & Answer 34

Q: Why do you call him "our Lord"?

A: Because-
not with gold or silver,
but with his precious blood-1
he has set us free
from sin and from the tyranny of the devil,2
and has bought us,
body and soul,
to be his very own.3
