I also disagree with you that the Church is receiving "messages" from Christ other than what is in the scriptures and what is already known to the Church by the Holy Tradition.

The church freed slaves held by Muslims.
“”There is no scriptural basis to oppose slavery; the scriptures do not condemn it””
The Salve trade tore husbands from wives,so scripture is against it
Therefore now they are not two, but one flesh. What therefore God hath joined together, let no man put asunder.Matthew 19:6
Child slavery is against Scripture also..
But Jesus said, Let the little children come to me and do not hinder them, for to such belongs the kingdom of heaven.Matthew 19:14
