Good to meet you.Bonsoir mon amie, I see you have met Sora, I do not believe we have been formally introduced as of yet allow me the honor: I am Seraphine, Christian Humanist, painter and art restorer, Classical pianist and Sora's wife and soulmate. Your ideas are well formulated and thought out I must say I agree with all you say here in regards to your question I believe that they can and are compatible however the reason why they may not be to some Christians is due to interpretation and people mirror the religion do you not agree? Here is one source to explain what Christian Humanism is: desales.edu/home/about/our-heritage/christian... and another from a more theistic centered view www.christianchronicler.com/history1/christia... now then in regards to Rubens this link shall help: http://www.myreproductions.com/peter_paul_rub... I too am honored to meet and speak with you.
I gave an answer to Sora about why I think Christian Humanism isn't as well known or as widely adopted as it should be.
I think the main reason is related to politics. Christian Conservatism is hugely influential in America and I don't think it's compatible with Christian Humanism. Fundamentalism is still pretty popular in a lot of places. Evangelistic mega churches are becoming more popular. These versions are highly aggressive and divisive.
