The issue at hand—the reception of Communion by adulterers—has nothing to do with “the traditions of men.” It has to do with the words of Jesus Christ and the words of Saint Paul.

27“You have heard that it was said, ‘YOU SHALL NOT COMMIT ADULTERY’; 28but I say to you that everyone who looks at a woman with lust for her has already committed adultery with her in his heart. Matthew 5:27-28
The issue at hand is the Catholic Church putting itself as the arbitrator between God and man. That is false doctrine. The only arbitrator between God and man is the man Christ Jesus (1 Timothy 2:5).
