If you know anything about the Freemasons, you would know that that kind of information would not be easy public knowledge.
If you don't know anything about Freemasonry or very little, that is because that is what they want you know. Most people will ask, don't they drive those little cars? Yup.
I will provide more links at the bottom of the page for further reading but to get back to Tim Kaine. He professes to be a Catholic and that his "faith is very important to what he does." He is staunchly pro-abortion (100% rating from Planned Parenthood) and fully supports gay-marriage which are positions clearly in contradiction to the Catholic church.
In 1983, Cardindal Joseph Ratzinger, prefect of the Congregation for the Doctrine of the Faith, with the personal approval of Pope John Paul II, issued a Declaration on Masonic Associations, which reiterated the Church's objections to Freemasonry.The 1983 declaration states that "faithful who enroll in Masonic associations are in a state of grave sin and may not receive Holy Communion. ... the Church's negative judgment in regard to Masonic association(s) remains unchanged since their principles have always been considered irreconcilable with the doctrine of the Church (emphasis added) and therefore membership in them remains forbidden.
If you read up on Freemasonry, you will see that the underlying philosophy which guides its practices is a naturalistic deism/humanism. That humans can reach their full potential through harmonious living and service to each other. You might read this and think, "What's wrong with that?" The Christian SHOULD answer, our full potential is only obtained through salvation by Jesus Christ. The ultimate aim of life on Earth is to serve Our Lord and His Church according to Her precepts to face the final judgment.
This is where the Freemasons have infiltrated our church. Not by some grand conspiracy (which I can't completely rule out), but by a piece by piece obfuscation of the essential truths of Christian life. There is a God. He has been revealed. His Truth is eternal. We don't get to pick and choose which truths we will espouse, and finally IN NO WAY will providing for the common good ever be a substitute for faith in Jesus Christ and the One, Holy, Catholic, and Apostolic Church.
Tim Kaine, Nancy Pelosi, Joe Biden, etc. are all symptoms of the disease caused by bad preaching, bad formation, and bad discipleship. Being a Good Samaritan does not supercede the Gospel.
#1) Love the Lord your God (if you're Catholic, it means you also love His Bride, the Church)
#2) Love your neighbor as yourself

You can spend forever on google reading and watching videos on both sides of this issue.
