A true Christian will not make a toxic cake
A true Christian will not make a toxic cake.
A true Christian would not make an inferior cake.
A true Christian would render unto Caesar by making a good cake.
Then deliver that cake with the message that it is filled with Christian love. blessings, and a superabundance of prayers for their salvation from sin.
Then, a cynical-minded Christian would quietly chuckle thinking of all the things the partiers would imagine that meant about the contents of the cake. But not mean-spiritedly.
It's not about the cake, of course, but if the devil can use it so can the angels.
Theology matters.
