Cling to the Lord Your God

Therefore, be very strong to keep and to do all that is written in the Book of the Law of Moses, turning aside from it neither to the right hand nor to the left, that you may not mix with these nations remaining among you or make mention of the names of their gods or swear by them or serve them or bow down to them, but you shall cling to the Lord your God just as you have done to this day.  Joshua 23:6-8

The below is apropos because of the recent desire to invite Muslim teachers and speakers into Christian churches.  The opponents want to know why Christians do not worship all the gods or at least use some of the ceremonies in their worship.  The answer is simple: we pay homage to whom it is due.

For they propose these questions: "If you are in earnest about religion, why do you not serve and worship the other gods with us, or share your sacred rites with your fellows, and put the ceremonies of the different religions on an equality?"

 

We may say for the present: In essaying to approach the divine, the Supreme Deity suffices us,—the Deity, I say, who is supreme, the Creator and Lord of the universe, who orders and rules all things: in Him we serve all that requires our service; in Him we worship all that should be adored,—venerate that which demands the homage of our reverence.  For as we lay hold of the source of the divine itself from which the very divinity of all gods whatever is derived, we think it an idle task to approach each personally, since we neither know who they are, nor the names by which they are called; and are further unable to learn, and discover, and establish their number.

And if those gods are indeed real, prove it.

Now we have made this statement, on the hypothesis only that it is clear and undeniable, that besides the Ruler and Lord Himself, there are still other beings, who, when arranged and disposed in order, form, as it were, a kind of plebeian mass.  But do not seek to point out to us pictures instead of gods in your temples, and the images which you set up, for you too know, but are unwilling and refuse to admit, that these are formed of most worthless clay, and are childish figures made by mechanics.  And when we converse with you on religion, we ask you to prove this, that there are other gods than the one Supreme Deity in nature, power, name, not as we see them manifested in images, but in such a substance as it might fittingly be supposed that perfection of so great dignity should reside.
