An idol is an idol

(J. C. Philpot, "Prevailing Pleas" 1865)

"Son of man, these leaders have set up idols
 in their hearts!
They have embraced things
 that lead them into sin." Ezekiel 14:3

An idol is an idol, whether worshiped inwardly
in heart, or adorned outwardly by the knee.

Therefore, give the people of Israel this message
from the Sovereign Lord: "Repent and turn away from
your idols, and stop all your loathsome practices. I,
the Lord, will punish all those, both Israelites and
foreigners, who reject Me and set up idols in their
, so that they fall into sin." Ezekiel 14:6-7
