The phrase without wax is an English translation of sin cera. When sculptors of stone would mess up they would cover there mistake by filling it with wax. A true statue was then said to be without wax. This where the English word sincere comes from. Sin “without” cera “wax”. So to say without wax means sincerely or true.
“As the stories go in the Roman world, it wasn’t unusual for pottery to crack after being placed in an oven to cure. A well-respected potter would inspect his pottery after firing, and if any cracks were found, the vessel would be discarded and he would start over. Of course, this would increase the price and value of the piece of pottery. Less reputable potters would rub wax into the cracks and then paint over the imperfections and blemishes and pass off their pottery as perfect but sell it for cheaper prices than the fine quality pottery. Once the strategy behind the trading wars was found out, the honorable pottery merchants placed signs over their stores and on their pottery bearing the phrase- sine cera—meaning, in Latin, without wax. It is the same idea in modern retail where products are stamped as “authentic” or “genuine”. unknown
The highest compliment we can pay another person is sincerity. It is possible to give an honest appraisal without being rude. Speaking the truth in love is the foundation of strong interpersonal relationships. If we wax over our words in order to appear to be what we think others would like to see, we will only promote further mistrust when the wax eventually melts and our insincerity is shown.
“Love must be sincere” (Romans 12:9 a). Mean what you say, say what you mean, and don’t be mean saying it!” (Without Wax 2014)
The phrase is normally used after an i love. I. E. I love you without wax, mean I love you sincerely or without blemishes.
