is it to bring the crucifiers to justice, fire away.
First things first. If you want to bring a highly protected strongman to justice you have to first break into his fortress like a thief in the night while everyone is sleeping, overpower him, gag and bind him hand and foot, ransack his fortress, and get away clean with all of his possessions before the sun comes up. Then you can drag his humiliated ass before the Judge. And Justice will follow.
"The way the truth and the life" is a reference to the truth that there is only one way to interpret and comply with Divine instruction that fulfills the promise of eternal life here and now on Earth.
"No one comes to the Father except through me" is the fact that there is no other way, except the way that Jesus taught, to comply with Divine instruction that prepares the fragile and extremely tiny human mind to perceive God, stand in his presence, whether near or far, and hear his words.
So if you want to bring 'the crucifiers' to justice one must first establish that Christian teaching about Jesus is false, the way the Jewish and the way the Muslims screw around over what to eat isn't the right way to comply with the Law which proves that all of their claims to moral authority based their professed adherence to biblical teaching is patently false. This has already been done.
Jesus didn't command anyone to worship a trinity or celebrate his bloody death on an altar. Moses didn't command Jews, Muslims, or anyone, to eat or abstain from certain foods. Its all brazen lies. They all claim to be experts on the moral law who maintain fidelity to biblical teaching, forgeries or not, without knowing the meaning of the words or subjects about which they are so dogmatic. The words in the law are figurative, the subjects hidden, and not necessarily directly connected to the literal meaning of the words used. If you look and look and keep on looking you will find it.
What then? Now that the truth, for so long unfruitful, has finally come to light all thats left for the persecuted to do is the right thing. So if you know the right course to take, just shut up and do it.
Do not cower before the accursed. Do not submit to specious lies. Stand up and walk like a man.
