catholics should not kid themselves in order to reject the Truth of what The Word of God declares. Saying magic words is a catholic schtick. A Born from Above Christian knows with the heart man believes in order to receive God’s Life in them. They that walk after the flesh to try and eat Jesus to get Him inside of them are contrasted with those thaqt walk after the Spirit. The Spirit gives Life to the spirit. The belly gives life to the flesh. The proof is at the sermon of Peter on Pentecost, and in the house of Cornelius when Peter preached there. with the heart those receiving God’s Life believed unto righteousness.
Paul writes to Christians over and over telling them that they're not living like Christians and therefore not following Christ in spite of Christ Himself saying we need to take up our cross and follow him. Christ Himself said that since He cut off the original branch we should beware lest we too be cut off even after we were grafted in.
The vast majority of Protestant folks ignore all of that and have degenerated into nothing more than Wicca with a "wink, wink, nudge, nudge," while saying "Jesus Christ" but teaching Do what thou wilt shall be the whole of the Law. Claiming to be led by the same Holy Spirit Protestant doctrine, all Protestant and Protestant derived doctrine, clearly states is imperfect and inept is no different than claiming to be led by whichever spirit is hanging from a nearby tree.
People who have, for example, changed their beliefs and interpretation of Scripture to the degree that they accept the murder of infants in the womb as long as it's called "contraception" are people who are under a strong, diabolical, delusion, not people understand Scripture and who are following Christ.
