"I humbly caution us all (myself included) to beware of and resist temptations to judge those who judge us.
As Tiber hinted, they believe that they are defending the sanctity and holiness of God's own message, which as His Elect, they alone grasp in fullness.
I believe it is unwise to say of these, our brothers and sisters, that they are "hateful" or subject to judgment for failing to "love their brothers who they can see." To do so is to do the very same thing--and perhaps even more so: for we Catholics profess that all Christians are indeed our brothers and sisters in Christ--whether they know it, or like it, or not.
We must have the same attitude that was in Christ, and humble ourselves as obedient servants.
We must pray and hope that their motivations are for love of God and zeal for his truth, even when its execution offends us. We must encourage every step taken in understanding and in faith. We must avoid breaking the bruised reed. We must not extinguish the smoldering wick.
No argument, no pleading, no appealing to reason, no appealing to the very same authority that they claim as their sole authority can soften their hearts. Knowing this, would anyone honestly expect that sarcasm or insult (no matter how sugar-coated or no matter how indirect) will do so?
Rather, if we are to witness to the truth, let it be this: that we love one another. As is true for all of us, it is by the Holy Spirit that any come to the Table of the Lord. It is by God's grace that they will someday come into full communion with the remainder of the holy Church that they (and often we also) fail to recognize as the mystical body of Christ (whether they come while in this life or the next).
If *we* say that we know God who we cannot see, and hate our brothers who we can see, there is no truth in us.
This I submit with the knowledge of and repentance from my own sins toward my brothers.
With humbly prayer to you for your prayers to Jesus, I remain
