We have complete faith that God will judge us based upon what is in our hearts and not on the misjudgements of others.
...while we can demonstrate with certainty that abstaining from these acts would not be sinful at all.
Abstaining from humility might not be sinful in and of itself, but how do you think He will respond to you having judged the faith of His brothers?

Christian liberty is great, but it doesn’t give absolute freedom. There are certain acts which are evil, no matter what is in a person’s heart when they commit them. Now, I’m not the one who determines what those acts are, but certainly they do exist. If all that matters is what is in your heart, then why will many people who believed that they served God be told, when the time comes, that He never knew them?

Where have I “judged the faith” of others? Where have I said so-and-so is going to hell, or they have no faith, or some statement like that? I’m making a theological argument, exhorting others to, what I believe, is a more sound worship of God. Or is what is in my heart not important after all?
