and additionally they don’t have to have a relationship with God and His Son, Jesus, because the false doctrine of "once saved, always saved" takes care of that on their behalf.

By relationship do you mean popping in for a quick Saturday mass so you don't miss Sunday football?

Or are you referring to confessing your sins to a man?

Or maybe praying to some other intercessory other than Jesus like Mary, the saints, etc.?

Relationship with God? More like relationship with the church.

Most Masses are early enough to make it home for kickoff. You mean Protestants never look at their watches during their service?

Show me in Scripture where it says worshipping God for even just a moment is a bad thing.

Or are you referring to confessing your sins to a man?

James 5:16 "Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective". Do you confess your sins to another person as instructed by Scripture?

Or maybe praying to some other intercessory other than Jesus like Mary, the saints, etc.?

1 Tim 2:1 "I urge, then, first of all, that petitions, prayers, intercession and thanksgiving be made for all people?" Pray tell, there is nothing wrong with asking others who are in Christ to pray for you, is there?

Relationship with God? More like relationship with the church.

Yes a relationship with God and His Church.

[Cronos]

Having a personal relationship with God is more than just confessing that He is Savior and Lord and nothing else. Having a relationship with say your spouse is not just saying "you're my mate." and nothing else.

Analogously, having a personal relationship with Our Lord and God, is more.

We Catholics agree that we must have a relationship with God and that we cannot work our way to heaven. But we don’t agree that our behaviors aren’t important. In fact, as we will see, Scripture indicates that, indeed, a relationship with God calls us to be people of moral behavior and good works—that is to say, religious people. Christianity is itself a religion and to be religious means to live morally and to do good works. Scripture teaches that, in essence, to be in a personal relationship with Jesus means to be religious.

Refer 1 Tim 3:16, James 1:26, James 1:27, 1 Tim 5:4, 2 Tim 3:1-5, Gal 4:8-9.

The word "relationship" isn't in the Bible but we are exhorted to KNOW God and yet 1 John 4:8 "He who does not love does not know God; for God is love" -- to know God is to know LOVE, to love others.

And Paul emphasises in Titus 1:15-16 that knowing God, i.e. having a relationship with Him is demonstrated in our very deeds "To the pure all things are pure, but to the corrupt and unbelieving nothing is pure; their very minds and consciences are corrupted. They profess to know God, but they deny him by their deeds; they are detestable, disobedient, unfit for any good deed"

Remember that having this personal relationship with God is living in and breathing in His Word, living a life in accordance with His precepts and commands, and showing love.

Christianity, this personal relationship with God is demonstrated in religious lives and our behaviour

James 26-27

And if anyone thinks himself to be religious, not restraining his tongue but deceiving his own heart, that man's religion is vain. Religion pure and undefiled before God the Father is this: to give aid to orphans and widows in their tribulation, and to keep oneself unspotted from this world.
