I think that lay-people should use the tried and true Sign of the Cross rather than commanding and binding demons. We should leave the commanding and binding to the priests.
“And let him come who would test by experience what we have now said, and in the very presence of the deceit of demons and the imposture of oracles and the marvels of magic, let him use the
Sign of that Cross which is laughed at among them, and he shall see how by its means demons fly, oracles cease, all magic and witchcraft is brought to nought.” - St Athanasius the Great
“…whereas by the
sign of the Cross all magic is stopped, and all witchcraft brought to nought, and all the idols are being deserted and left, and every unruly pleasure is checked, and every one is looking up from earth to heaven…” - St Athanasius the Great
“…but what there is is now fading away: and demons, so far from cheating any more by illusions and prophecies and magic arts, if they so much as dare to make the attempt, are put to shame by the
sign of the Cross.” - St Athanasius the Great
“And whereas formerly demons used to deceive men’s fancy, occupying springs or rivers, trees or stones, and thus imposed upon the simple by their juggleries; now, after the divine visitation of the Word, their deception has ceased. For by the
Sign of the Cross, though a man but use it, he drives out their deceits.” - St Athanasius the Great
“If we are striving to drive out demons,
we use the Cross, and it is also of aid in healing sickness.” - St John Chrysostom
