The relativistic description of the structure of composite states can be either within the field theoretical framework of the 4D Bethe-Salpeter equations, defined in the Minkowski and Euclidean spaces, and also within the three-dimensional reduction to the light-front hyperplane, where the hadrons are eigenstates of the interacting mass operator. The relation between the Light-Front and 4D descriptions in Minkowski, Euclidean and in between, for the composite state will be discussed, resorting also to an integral representation of the Bethe-Salpeter amplitude. The discussion will be illustrated by examples of two-boson bound state and a quark-antiquark bound state forming a mock pion. The three-body problem will also be briefly addressed in the different descriptions.
