"why do you say that? I want to help as many souls as I can to Heaven."
I think I'm primarily leaning on St. Paul on this one.
In the first chapter of 1 Corinthians, we get this: "the word of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. . . . For since in the wisdom of God the world through its wisdom did not come to know God, God was well-pleased through the foolishness of the message preached to save those who believe. For indeed Jews ask for signs and Greeks search for wisdom; but we preach Christ crucified, to Jews a stumbling block and to Gentiles foolishness, but to those who are the called, both Jews and Greeks, Christ the power of God and the wisdom of God. Because the foolishness of God is wiser than men, and the weakness of God is stronger than men."
Then later in the same book, we get this: "to those who are without law, [I became] as without law, though not being without the law of God but under the law of Christ, so that I might win those who are without law." For a picture of what this looked like in practice in St. Paul's own life, consider Acts 17.22-32 (addressing the Areopagos, in which "when they heard of the resurrection of the dead, some began to sneer") and Acts 24.24-25 (speaking to the Roman governor, during which, "as he was discussing righteousness, self-control and the judgment to come, [the governor] became frightened" and sent him away).
