As I understand it the internal forum is what it has always been .  No general "rule"  is promulgated   .  Each human person is respected and his / her awareness of interior intention is honored  .  The essential dignity of the person must always be honored . To do otherwise is to contradict the Lord God .  When one fails to respect person it may be due to other reasons or causes .  So it is not up to you or me to impute deliberate willfulness .  
Before Constantine soldiers who followed the way of Jesus didnot have to be told to quit the army .  After Constantine the church lost a valuable understanding.   And church as institution has overwhelmed the far deeper aspects .  
Let God deal with "willful self deception"  .  Just present one's self at the Table of the Lamb because he
said to .  The beyond generous love of God is definitely confusing to mere mortals !
