Christians established orphanages, charities for the poor and homeless, hospitals and schools and organisations like the Red Cross and Salvation Army and many humanitarian organisations.
Here is a list of some of the ethics and morals Christ taught. These things are freely available on the internet so you can verify them yourself. There is overwhelming evidence of how Christ’s teachings renewed society and created a better world. The ‘suns’ of all religions rise and set so there comes a time they become no longer relevant and fall into disunity. Then a new sun rises with the dawn of a new day and a new Manifestation.
Bible Gateway passage: Matthew 5-7 - New International Version
I was taught all these things in church. Any or all of these teachings renewed the spirit of the age.
In the 5th century,
Saint Augustine began his book
Our Lord's Sermon on the Mount by stating:
If any one will piously and soberly consider the sermon which our Lord Jesus Christ spoke on the mount, as we read it in the Gospel according to Matthew, I think that he will find in it, so far as regards the highest morals, a perfect standard of the Christian life.

Role of Christianity in civilization - Wikipedia
The Bible and Christian theology have also strongly influenced Western philosophers and political activists. The teachings of Jesus, such as the
Parable of the Good Samaritan, are among the important sources for modern notions of Human Rights and the welfare measures commonly provided by governments in the West. Long held Christian teachings on sexuality and marriage and family life have also been both influential and, in recent times, controversial. Christianity played a role in ending practices such as human sacrifice,
[6] infanticide and polygamy.
[7] Christianity in general affected the status of women by condemning
marital infidelity,
divorce,
incest,
polygamy,
birth control,
infanticide (female infants were more likely to be killed), and
abortion.
[8] While official Church teaching
[9] considers women and men to be
complementary (equal and different), some modern "advocates of ordination of women and other feminists" argue that teachings attributed to
St. Paul and those of the
Fathers of the Church and
Scholastic theologians advanced the notion of a divinely ordained female inferiority.
[10] Nevertheless,
women have played prominent roles in Western history through and as part of the church, particularly in education and healthcare, but also as influential theologians and mystics.
