Where in the world did you get that idea? It's you OSAS folks that complain God's Ten Commandments are too grievous,
which is what the old man of sin would say, not the new man in Christ Jesus...
Y'know why a bridegroom can stand at the altar anxious to publicly vow marital fidelity to his bride while a single, promiscuous man watching the whole affair recoils in horror at such an idea as "too grievous" a limitation?
Love.
Love for God is shown in keeping His commandments by those who find them anything but grievous, while those who make 10,000 excuses for why "
we can't keep the Ten Commandments" demonstrate their hatred for the idea of faithfulness to only God no less than the man who can't wait to seduce one of the bridesmaids after the ceremony.
