I think most people are Protestant for the same reason most people are Catholic. They were born that way. Some people change denominations, I even changed religion.
I am Episcopalian. I was born Methodist, became Episcopalian at age 14, became Baha’i at age 19, left the Baha’i Faith at age 49, went back to the Episcopal Church and am still there.
Obviously my life has involved spiritual search. Whether I become Roman Catholic or not is yet to be seen. I accept many Roman doctrines, such as Purgatory (I actually believed in that as a Baha’i), the Marian doctrines, Real Presence (Transubstantiation). I have a problem with “the whole enchilada” however.
See matthew Chapter 6 (from the DR)
60 These things he said, teaching in the synagogue, in Capharnaum.
61 Many therefore of his disciples, hearing it, said: This saying is hard, and who can hear it?
62 But Jesus, knowing in himself, that his disciples murmured at this, said to them: Doth this scandalize you?
63 If then you shall see the Son of man ascend up where he was before?
64 It is the spirit that quickeneth: the flesh profiteth nothing. The words that I have spoken to you, are spirit and life.
65 But there are some of you that believe not. For Jesus knew from the beginning, who they were that did not believe, and who he was, that would betray him.
66 And he said: Therefore did I say to you, that no man can come to me, unless it be given him by my Father.
67 After this many of his disciples went back; and walked no more with him.
68 Then Jesus said to the twelve: Will you also go away?
69 And Simon Peter answered him: Lord, to whom shall we go? thou hast the words of eternal life.
70 And we have believed and have known, that thou art the Christ, the Son of God.
Following the truth of Christ is hard. It was hard when he was Physically present. How much harder must it be today with all the noise of our modern culture?
I pray that you may find the truth and come home.
