Tactu qualitativo, as Cajetan expoundeth it, with a deadly touch; he thrusts not in his sting so far as to infuse the venom of that sin that is properly his sin,John 8:44, and with which he toucheth their spirits that become the serpent's seed. He toucheth them not so as the needle is touched by the loadstone; so as to partake of his devilish spirit, and to be wholly carried after him.
