a.) Kinism was not a first order doctrine related to salvation and so shouldn’t be front and center.
b.) Kinism was going to be a hurdle for their other friends making it difficult for children to find marriage partners.
I thought I would turn to the words of St. Chrysostom in order to demonstrate that Kinism is a first order doctrine and is related to salvation.
Speaking of those accursed who turn from God Chrysostom writes:
“Did they not trample kinship under foot, did they not forget their children, did they not forget the very God who created them.”
For if a man deserts. those who are united by ties of kindred and affinity, how shall he be affectionate towards others? Will it not have the appearance of vainglory, when benefiting others he slights his own relations, and does not provide for them? And what will be said, if instructing others, he neglects his own, though he has greater facilities; and a higher obligation to benefit them? Will it not be said, These Christians are affectionate indeed, who neglect their own relatives?
Wherefore? Because the latter, if he benefits not aliens, does not neglect his near kindred. What is meant is this: The law of God and of nature is violated by him who provides not for his own family. But if he who provides not for them has denied the faith, and is worse than an infidel, where shall he be ranked who has injured his relatives? With whom shall he be placed? But how has he denied the faith? Even as it is said, “They profess that they know God, but in works they deny Him.” (Tit. i. 16.) What has God, in whom they believe, commanded? “Hide not thyself from thine own flesh.” (Isa. lviii. 7.) How does he then believe who thus denies God? Let those consider this, who to spare their wealth neglect their kindred. It was the design of God, in uniting us by the ties of kindred, to afford us many opportunities of doing good to one another. When therefore thou neglectest a duty which infidels perform, hast thou not denied the faith?”
In terms of (b) above the only thing that might be said is that there will be a greater cost born by family members for a patriarch abandoning truth than will be born by family members if the patriarch stands by the truth.
If we will not love those who we are related to, how can we love the One who we can not see?
It’s sad that there are many people who deny the truth to their own hurt. Rejecting their own family for the sake of pragmatism. Going from embracing their own flesh and blood, extended family, county, state and nation to reducing everything to a public confession of Christ. God have mercy on their souls. We can only pray for their repentance.
