The article addresses your question perfectly.
If that’s what’s necessary, I’m fine. As a non-Catholic, I believe all of that and have done that which is listed, partaking in what Catholics call “sacraments”. While I was baptized as an infant, I knew nothing of what I committed to, so I was baptized (immersed) as an adult when I knew of what I professed.
Communion, also, is necessary, as are the other Scriptural requirements and character, conversatin and conduct attributes you’ve listed.
But as a non-Catholic, I no longer worship or pray to Mary or to the saints. Matthew 6 (which contains the “Our Father” and John 14 - 17 give several examples of Jesus telling us to ask of the Father in the Name of Jesus. I know of no instance in Scripture where we are to pray to Mary. And I do NOT adhere to the “as long as you believe in something” that Alex Murray referred me to on this thread. Jesus is the ONLY WAY.
But back to Baldwin. He is no deep theologian; he’s just trying to get people “in the door”. The next phase is “discipleship”, and any good church will take new believers and teach them the ways of God (via study of Scripture) so they can know the riches of Christ. Baldwin does not claim to do that; he’s just trying to get people to accept the message of salvation through belief in Jesus Christ.
