In Exodus 20:25, this signifies truths formed from good, or good in form, to signifies that nothing of self-intelligence should be involved in its forming. (Apocalypse Explained 391[21, 21])

222. But essential Divine worship in the heavens does not consist in going to church and hearing preaching, but in a life of love, charity, and faith, in accordance with doctrine; preachings in churches serve solely as means of instruction in matters of life. I have talked with angels on this subject, and have told them that it is believed in the world that Divine worship consists solely in attending church, listening to the preaching, observing the sacrament of the Supper three or four times a year, and performing other acts of worship according to the requirements of the church; also devoting special times to prayers, and at such times, behaving devoutly. The angels said that these are outward acts that ought to be done, but are of no avail unless there is an internal from which they proceed, which is a life in accordance with the precepts that doctrine teaches.
