Your arguments are based on what? Philosophy or God's word?
Matthew 28:19 is thought to be a spurious addition to Matthew based not only on the internal evidence of the NT, but manuscript evidence.
According to F.C. Conybeare, "Eusebius cites this text again and again in his works written between 300 and 336, namely in his long commentaries on the Psalms, on Isaiah, his Demonstratio Evangelica, his Theophany ...in his famous history of the Church, and in his panegyric of the emperor Constantine. I have, after a moderate search in these works of Eusebius, found eighteen citations of Matthew xxviii. 19, and always in the following form: "
"Go ye and make disciples of all the nations in my name, teaching them to observe all things, whatsoever I commanded you."

I am sure you know who Eusebius is. Also basing a doctrine of 1 verse is as you pointed out a tactic of cults.
Human bodies do not sleep when they die they decompose. You know dust to dust.
The Son did not procede from the Father, the Son was born of a woman.
Now, as to what I posted in the OP your one line dismissal only indicates you cannot address God's word since traditions are what drives Catholicism.
