I came across this today, this picture is from The Harp of God 1921, p113 which is an old Watchtower publication.
Watchtower 1989 May 1 p.23 says
“There are also inanimate objects that if venerated may lead to breaking God’s commandments. Among the most prominent is the cross. For centuries it has been used by people in Christendom as part of their worship.
… Soon God will execute his judgments against all false religions. Those who cling to them will suffer their fate.”
I wonder if the Watchtower was one of those false religions when it taught that Jesus was on the Cross?
