Although you guys use "liberal" as a profane word and try to paint your opponents as anti-God and anti-American with it, the definition of the word liberal hasn't changed. In this context, conservative means "tending or disposed to maintain existing views, conditions, or institutions" and liberal means "not bound by authoritarianism, orthodoxy, or traditional forms". If we put aside the fact that MAGA has hijacked Christianity for a political agenda, it's pretty clear that within the social, religious, and political context of his day, Jesus was astoundingly liberal; in fact, he was a revolutionary in every sense of the word.
Jesus was absolutely anti-establishment, radically liberal, and vehemently critical of the authoritarian establishment, aligning Himself instead with the poor, the oppressed, and others the establishment considered social outcasts. Jesus fiercely defied the ultra-conservative religious, political, and social power structures of the day, bringing a radically liberal theology to the masses, healing on the Sabbath, blessing outside of the rigid purity system, forgiving the sins of those condemned by the establishment, and calling for the liberation of women and minorities from their social, political, and religiously sanctioned oppression.
To the existing power structure, Jesus was a subversive that taught people that they do not need to conform to the strict and orthodox views of God, religion, and life that the corrupt establishment perpetuated. He condemned the ruling elite's greed, violence, their glorification of power, their amassing of wealth without social balance, their judging of others, their lifestyles, and their beliefs. He ferociously rebuked the religious right of His day for embracing the letter of the law instead of the Spirit, calling the Scribes and Pharisees hypocrites and vipers, and they assassinated Him for it.
Jesus was imparting a vision for a completely new world order, one based on compassion, equality, inclusion, forgiveness, tolerance, peace and love. His egalitarian vision for mankind was diametrically opposed to the authoritarian political, social, and religious structure of the day. He demanded nothing less than the complete transformation of all the laws and conditions of his world into those of the Kingdom of God. He wanted to empower all human beings with their divine identity in that Kingdom and he vehemently exposed the naked corruptions of the establishment's various forms of external power, especially the gender based and grossly patriarchal misogyny of the times.
He "astonished" people with a transforming vision in which all the lies of the corrupted establishment were unmasked and he called for profoundly radical changes to the existing social and political power structures. He was dangerous because He was shaking the very foundations of all of the false constructs of the corrupt establishment...and the people were listening to him.
This political, social, and religious revolutionary was imparting an egalitarian vision that was absolutely lethal to the conservative ruling elite of the day, both the Roman occupation's imposed order and the corrupted religious "mediators". It is for this that the ruling powers conspired to kill this dangerous Rabbi, the Romans crucified him to make an example of him for anyone who had been listening to his incendiary vision of equality and concerted effort for justice and compassion for all.
With revolutionary intent and passion, he was willing to die to bring about a complete transformation of the conditions of his world, and so by definition, anything even remotely resembling a genuine interpretation of His life, teachings, and intent, make it clear that He was a radically liberal progressive.
