catholic minds aren't on the Spirit given by God, but on the spirit given by men (the flesh) - the rcc. the rcc is not God (nor is it of God) and it doesn't have His Spirit to give to you.What we do is set our minds on the Spirit to stay in Christ and please God.
Romans 8 5 For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit. 6 To set the mind on the flesh is death, but to set the mind on the Spirit is life and peace. 7 For this reason the mind that is set on the flesh is hostile to God; it does not submit to God’s law—indeed, it cannot, 8 and those who are in the flesh cannot please God.
