Dr. Norman Vincent Peale, the noted author of The Power of Positive Thinking, served as senior minister from 1932-1984. Under his ministry Marble's influence reached national levels and became known as "America's Hometown Church." On November 19, 1961, Lucille Ball married her second husband Gary Morton in the church.[4] Following Peale's fifty-two year ministry, Dr. Arthur Caliandro served 25 years as the fifth senior minister of Marble Church. In all, he served 42 years on the pastoral staff. During Caliandro's tenure, MarbleVision, the media ministry of Marble Church, was founded, its first woman minister was ordained, and the first women elders received. In addition, the church added its first new stained-glass window in almost 100 years. In 2009, Dr. Michael B. Brown, former pastor of Centenary United Methodist Church in Winston-Salem, North Carolina, succeeded Dr. Caliandro as senior minister.
As Trump said, his pastor was Norman Vincent Peale.
From Wikipedia, under Donald Trump:
In 1983, the Reverend Norman Vincent Peale, described in a New York Times profile as Trump's "pastor" and "family minister", said that Trump was "kindly and courteous in certain business negotiations and has a profound streak of honest humility."[26] Trump calls his own book The Art of the Deal (1987) "my second favorite book of all time," and has told campaign audiences: "Do you know what my first is? The Bible! Nothing beats the Bible."[427][428] Declining to name his favorite Bible verse, Trump said "I don't like giving that out to people that you hardly know."[425]Trump says that he is of Presbyterian faith.[422] In an April 2011 interview on the 700 Club, he commented: "I'm a Protestant, I'm a Presbyterian. And you know I've had a good relationship with the church over the years. I think religion is a wonderful thing. I think my religion is a wonderful religion."[423][424] Trump told a 2015 South Carolina campaign audience he attends Marble Collegiate Church, where he married his first wife Ivana in 1977. The church has said he is "not an active member."[425] Trump has said that although he participates in Holy Communion, he has not asked God for forgiveness for his sins. He stated, "I think if I do something wrong, I think, I just try and make it right. I don't bring God into that picture."[426]
Peale began as a Methodist and became Reformed.
Trump's mother, Mary MacLeod was from Scotland, and her family's roots, if one goes by her grandparents who were married in the Free Church of Scotland which united with the United Presbyterian to form the United Free Church, was PresbyterianISH.
So, his family religious background, coming from his mother, would best have translated to her as Presbyterian, and she probably communicated that to her son.
But I have Presbyterians and Lutherans who attend our church, and they would tell people that is what they are. They put up with me, I suppose. :>)
A story told by Walter Martin from an article by His daughter:
“I’ll never forget the time when my teacher, Donald Grey Barnhouse, told me of a luncheon he had with Norman Vincent Peale-who was then riding the crest of the wave on the power of positive thinking. They had chatted for a few minutes when Peale unexpectedly remarked, “I’d like a candid answer, Donald. I know you’ll give me one. What do you really think of what I’ve written on the power of positive thought?”
Donald Barnhouse was quiet for a moment before replying, “Well, I can only tell you what a great many clergymen have said to me.”
“And what is that?” asked Peale.
“Paul is appealing, but Peale is appalling,” said Barnhouse, irrepressible as ever. “You have forgotten the most important thing. Before anyone can think positively, they must think negatively.”
“What do you mean by that?” Peale asked.
“Look,” said Barnhouse, “I am a sinner. Negative or positive?”
“Negative.”
“I am a lost sinner. Negative or positive?”
“Negative.”
“I am going to eternal judgment. Negative or positive.”
“Negative.”
Dr. Barnhouse smiled, “Those are three negative propositions, without which, you cannot think positively. ‘Believe on the Lord Jesus Christ and thou shalt be saved’ (Acts 16:31). But if you don’t think the first three, you’ll never get to the fourth.”
“I never thought of it quite that way before,” answered Dr. Peale, rather disturbed.
“You must write a new book,” said Dr. Barnhouse, “The Power of Negative Thinking.”
“I can’t do that; it would ruin me!”
“Get out the truth,” said Barnhouse. “The Lord will take care of it.”
