Many Protestants seem to dislike crucifixes, so they only use crosses. Now, it seems like the more modern Protestants don’t even like crosses in their churches either.
This makes no sense to me. In 1 Corinthians 1:23 Paul was very clear when he wrote, “we preach Christ crucified.”
I’m not say we don’t need to preach Jesus risen, but I think we should do both.
Many of us tend to be opposed to the idea of relics - practiced in some world religions.
Remains and objects associated with holy people are held sacred in many religions. Learn about relics and their significance.

As for preaching the Gospel and the cross of Christ - we do embrace the following
1 Cor 1:
18 For
the word of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. 19 For it is written:
“I will destroy the wisdom of the wise,
And the understanding of those who have understanding, I will confound.”
1 Cor 1:22 For indeed Jews ask for signs and Greeks search for wisdom; 23 but we preach
Christ crucified, to Jews a stumbling block, and to Gentiles foolishness,
1 Cor 2:And when I came to you, brothers
and sisters, I did not come as
someone superior in speaking ability or wisdom, as I proclaimed to you the testimony of God. 2 For I
determined to know nothing among you except Jesus Christ, and Him crucified. 3 I also was with you in weakness and fear, and in great trembling, 4 and my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power, 5 so that your faith would not rest on the wisdom of mankind, but on the power of God.
1 Cor 11:23 For I received from the Lord that which I also delivered to you, that the Lord Jesus, on the night when He was betrayed, took bread; 24 and when He had given thanks, He broke it and said, “This is My body, which is for you; do this in remembrance of Me.” 25 In the same way
He also
took the cup after supper, saying, “This cup is the new covenant in My blood; do this, as often as you drink
it, in remembrance of Me.” 26 For
as often as you eat this bread and drink the cup, you
proclaim the Lord’s death until He comes.
So our "memorial" of His death is in the Communion service and our weekly reminder is on Sabbath as He died at the start of Sabbath and was in the Tomb on Sabbath. No wonder then that our Communion service is also on Sabbath.
