What is the difference between humanism and the teachings of the medieval catholic church?

i dont know for sure if this will helpChristian humanism begins with the moral teachings of Christ and embraces a religious belief that affirms humans are made in the likeness of God, which is the basis for personal worth. Christian humanism has evolved from a desire to revitalize and reform the Roman Catholic Church to activism on behalf of human rights based on a dynamic relationship with God and Christian teachings. The "liberation theology" preached and practiced by the clergy and faithful during mid-20th century periods of brutal injustice in Central America and apartheid in South Africa is an example of Christian humanism in action. The belief that human history is determined by the strength of the relationship to God unites faith and moral behavior. Christian humanism argues for the compatibility of Christian and humanist principles as opposed to the negative views about religion in secular humanism.
