“And lead us not into temptation”
“Herein it is shown that the adversary can nothing avail against us, unless God first permit him.” -St. Cyprian of Carthage
“The Lord is able, who has taken away our sins and forgiven our debts, to guard us against the snares of the devil, who is wont to produce sin in us. Hence it follows, ‘And lead us not into temptation,’ such as we are not able to bear, but like the wrestler we wish only such temptation as the condition of man can sustain.” -Pseudo-Augustine
“It is impossible not to be tempted by the devil, but we make this prayer that we may not be abandoned to our temptations. Now that which happens by Divine permission, God is sometimes in Scripture said to do. And in this way by hindering not the increase of temptation which is above our strength, he leads us into temptation.” -Titus of Bostra
“The Lord commands us to pray, ‘Lead us not into temptation,’ that is, let us not have experience of lustful and self-induced temptations. . . . James teaches those who contend only for the truth, not to be unnerved by involuntary and troublesome temptations, saying, ‘My brethren, count it all joy when ye fall into divers temptations’ (Jas 1:2).” -St. Maximus of Turin
“God does not of Himself lead a man [into temptation], but suffer him to be led from whom He has withdrawn His aid.” -St. Augustine
“It is one thing to be led into temptation, another to be tempted; for without temptation none can be approved, either to himself or to another. . . . We are then led into temptation when such temptations befall us as we are not able to resist. When then we say, ‘Lead us not into temptation,’ what we ask is, that we may not, deserted by His aid, either consent through the subtle snares, or yield to the forcible might, of any temptation.” -St. Augustine
